  1. Think about: Describe the forces and feelings you have experienced on a rollercoaster or amusement park ride. You may also start your sentences with “I wonder…” PUT YOUR NAME ON YOUR NEW PACKET!!!!! Example: On a spinning ride I feel like I am about to fly out of the side of the chair. On a rollercoaster I think I am going to “lose my stomach”. It feels like my insides are moving up and down. On a dropping ride I think I am going to hit the ground, but I stop really suddenly with a jolt and am pressed into my seat. Friday 11/30/2012

  2. What is an amusement park vs. a theme park? How are they similar? How are they different? A theme park is a type of amusement park which is built around one or more “themes”. Similar- They don’t travel like a fair/circus; have rides and entertainment attractions; are more elaborate than a playground or park Different- A theme park has different sections/islands devoted to telling a story; lots of design elements; rides all go with the theme of the park

  3. Amusement and Theme Parks • TV Coverage of Theme Parks • Wizarding World of Harry Potter • Universal Studios Orlando • Despicable Me! • Read “The Story – Part I: Fairs and Horses” on your own (Thrill Ride! pages 1-2). • Discuss questions #1-4 (also on page 2 in Thrill Ride! booklet) • Write your best answer on page 1 in the packet • Present ideas to the class

  4. Group Work & Sharing Session 2. Is it harder to get a stopped roller coaster to move, or to keep it moving? • Explain why. 3. When you are riding a roller coaster—or in a fast automobile—that is rounding a sharp turn, you feel as if you are about to be thrown out of your seat. • If the door were about to fly open at that moment, and you were not wearing your seat belt, which direction would you go? • Why do you think this? 4. Which has more energy, a roller coaster almost stopped on top of the first hill, or one that is moving at its maximum speed at the bottom of the first hill? • Explain your reasoning.

  12. Objective 12/04/2012 Page 60 SWBAT connect Newton’s 3 Laws of Motion to their everyday lives and measure it through application. Jumpstart • How can you tell when an object is moving? • How would you describe the motion of a football thrown by a quarterback from the time when it is in his hands, to the time the receiver catches it down the field? (Use words like: speed, acceleration, falling, rising, no motion)

  13. An object is moving (in motion ) when its distance from another object (reference point) is changing • ~ In QB hands- no motion ~ Throwing- ball in motion, gaining energy from arm ~ Rising in Air- changes speed; slows down (negative acceleration) as it rises to the peak point ~ Falling in Air- changes speed; speeds up (positive acceleration) as it falls into hands ~ Receiver catches- no motion

  14. Newton’s 1st Law Notebook Page 61 Packet 7 Page 2

  15. Packet 7, Page 2 • Motion- a change in the location of an object • An object is in motion if it changes position relative to a reference point • Reference Point- a place or object used for comparison to determine if something is in motion • Its position does not change • THINK ABOUT IT: You are riding on a school bus, and another bus is next to yours. When the other bus starts to move slowly, what do you see/feel? • You feel like you are moving backwards!

  16. Motion: Think about it… • You are in a virtual ride (sitting, but the seats may move) or an IMAX movie. What do you usually “feel”?? Why?? …your brain interprets the movement of the objects on the screen in relation to your body, and is tricked into thinking that you are moving!

  17. 1. Inertia: the tendency of an object to resist changes in its motion 2. All objects have inertia. More mass = more inertia = harder it is to change its motion • 4.1- TSW use examples to explain the concept of inertia in everyday situations • Soccer ball sitting at rest on a field, Two teams playing tug of war, trains and boxcars, bug and windshield, shuffleboard court, hitting a golf ball

  18. Newton’s First Law of Motion-Real-Life Examples- Balance/Unbalanced Forces • Soccer ball sitting at rest on a field. • The soccer ball, as it sits still, has balanced forces acting upon it. It will continue to sit on the field until a soccer player comes and exerts an unbalanced force on the ball, and it flies through the air. Two teams playing tug of war. They are both exerting equal force on the rope in opposite directions. This balanced force results in no change of motion.

  19. Newton’s First Law of Motion-Real-Life Examples- Mass & Inertia • Train and Boxcars. • Massive boxcars were sitting at rest. They have a great deal of inertia and it takes a large force to change their motion. Once they are moving, it takes a large force to stop them. • Bug and Windshield. • On your way to school, a bug flies into your windshield. Since the bug is so small, it has very little inertia and exerts a very small force on your car (so small that you don’t even feel it).

  20. If objects in motion tend to stay in motion, why don’t moving objects keep moving forever? • Things don’t keep moving forever because there’s almost always an unbalanced force acting upon it. A shuffleboard sliding across the ground slows down and stops because of the force of friction. If you hit a golf ball upwards it will eventually slow down and fall because of the force of gravity.

  21. In outer space, away from gravity and any sources of friction, a rocket ship launched with a certain speed and direction would keep going in that same direction and at that same speed forever.

  22. Page 2 • Examples of Newton’s First Law of Motion in your life • Come up with examples of when the Law: “Objects in motion tend to stay in motion, and objects at rest tend to stay at rest, unless acted upon by an outside, unbalanced, force.” • Do your best to identify what the “unbalanced” force is • HINT: ALL moving and stationary objects display Newton’s First Law of Motion!

  23. Review of Newton’s 1st Law of Motion • “Objects in motion tend to stay in motion, and objects at rest tend to stay at rest, unless acted upon by an outside, unbalanced, force.” • When I put my paper on the table to do homework, it stays there. • Objects at rest want to stay at rest! • Moving heavy furniture when rearranging my room. • Objects at rest want to stay at rest! • When I punt the football, it flies through the upright goal! • Objects change motion when adding at unbalanced force. • When my car runs out of gas and I have to push it. • Objects at rest want to stay at rest!

  26. Objective 12/05/2012 Page 62 SWBAT connect Newton’s 3 Laws of Motion to their everyday lives and measure it through application. Jumpstart Give THREE examples of when Newton’s first Law of Motion (aka the Law of Inertia) has been helpful in your life. 1. 2. 3.

  27. Newton’s 2nd Law Notebook page 63 Packet Page 3

  28. 4.6- TSW provide evidence to demonstrate the relationship between force and motion. • Force causes acceleration. More force = More acceleration. • Massive objects resist acceleration. More massive = Less acceleration. • Same force on objects of different masses = different accelerations. • Unit for force: Newton • Bullet, glacier, waterskier

  29. What does F = ma mean? 1. Imagine a ball of a certain mass moving at a certain acceleration. This ball has a certain force. 2. Now imagine we make the ball twice as big (double the mass) but keep the acceleration constant. F = ma says that this new ball has twice the force of the old ball. 3. Now imagine the original ball moving at twice the original acceleration. F = ma says that the ball will again have twice the force of the ball at the original acceleration.

  30. More about F = ma- Page 3 4. If you double the mass, you double the force. 5. If you double the acceleration, youdouble the force. 6. What happens if you double the mass and the acceleration? (2m)(2a) = 4F Doubling the mass and the acceleration quadruples the force. 7. What if you decrease the mass by half? How much force would the object have now? (1/2m)(2a) = 1F

  31. What does F = ma say? F = ma basically means that the force of an object comes from its mass and its acceleration. 9. Something very small (low mass) that’s changing speed very quickly (high acceleration), like a bullet, can still have a great force. 8. Something very massive (high mass) that’s changing speed very slowly (low acceleration), like a glacier, can still have great force. 10. Something very small changing speed very slowly will have a very weak force.

  32. How can you change the acceleration of an object? 11. How can you change the acceleration of an object? Acceleration = Force Mass • Change the Force on the object • Change the force on the object • Increaseforce = increaseacceleration • Decreaseforce = decreaseacceleration • Change the Mass of the object • Change the mass of the object • Decreasemass = increaseacceleration • Increasemass = decreaseacceleration

  33. Use the equation F=ma to solve the following: • Mike's car, which weighs 1,000 kg, is out of gas. Mike pushes the car to a gas station, and he makes the car go 0.05 m/s2. • How much force is Mike applying to the car? • 50 Newtons

  34. Newton’s 2nd Law- Real Life Examples of F=ma A 52 kg water skier is being pulled by a speedboat. The force causes her to accelerate at 2 m/s². Calculate the net force that causes this acceleration. Force = 52 kg x 2 m/s²  104 N

  35. Newton’s 2nd LawF=ma What is the net force on a 1,000 kg elevator accelerating at 2 m/s²? • Force = 1,000 kg x 2 m/s²  2,000 N What net force is needed to accelerate a 55 kg go cart at 15 m/s²? • Force = 55 kg x 15 m/s²  825 N Homework: Page 4 “Off to the Races”

  36. Thursday

  37. Objective 12/06/2012 Page 64 SWBAT connect Newton’s 3 Laws of Motion to their everyday lives and measure it through application. Jumpstart Answer each question. Then, say which Law of Motion is being described. A car parked on a hill may start to roll backwards because of • an unbalanced force. • a balanced force. Which situation would cause the greatest acceleration? • Applying a force of 12 N to an object that is 1000 kg. • Applying a force of 10 N to an object that is 1000 kg. • Applying a force of 12 N to an object that is 100 kg. • Applying a force of 10 N to an object that is 100 kg.

  38. Newton’s 3rd Law Notebook Page 65 Packet Page5

  39. “For every action there is an equal but opposite reaction” • Action-Reaction pairs of forces For every force acting on an object, there is an equal force acting in the opposite direction. Runner and starting block, rocket taking off, skateboarding, stubbing toe, sitting in your seat

  40. Classifying Movement: Page 5 4.3- TSW describe the following interactions: speed, velocity, and acceleration. • Speed- How fast an object moves; NOT what direction • Formula: speed = distance/time • What are some units of distance? Time? • Instantaneous speed- speed at one instant (speedometer) • Constant “uniform” speed- speed doesn’t changeover a period of time • Average speed- speed of an object as it moves over a period of time • Formula: average speed = total distance total time • Velocity(def)- The rate at which an object changes direction.

  41. Classifying Movement: Acceleration- Page 5 • Acceleration- a change in speed or direction • Positive Acceleration- speeding up/ increasing speed • Negative Acceleration- “deceleration”; slowing down/decreasing speed Test your understanding: • If a car turns a corner going a “constant speed” of 25 mph, is it accelerating? Why? • Is a ferris wheel accelerating? Why? • Is the moon accelerating? Why? ONLINE HOMEWORK Page 6- “From Here to There”

  42. Newton’s Third Law of Motion-Real-Life Examples • Runner and Starting Block. • As each runner pushes off, the starting block is pushed back (not enough to measure). • At the same time, the runner is pushed forward. • The runner and the earth are pushed in opposite directions.

  43. Rocket taking off • Action = pushes down on the ground with the force of its powerful engines • Reaction = ground pushes the rocket upwards with an equal force. • If this upward thrust exceeds the weight of the vehicle, up we go!

  44. Real-life Examples What happens if you are standing on a skateboard or a slippery floor and push against a wall? You slide in the opposite direction (away from the wall), because you pushed on the wall but the wall pushed back on you with equal and opposite force. Why does it hurt so much when you stub your toe? When your toe exerts a force on a rock, the rock exerts an equal force back on your toe. The harder you hit your toe against it, the more force the rock exerts back on your toe (and the more your toe hurts).

  45. Newton’s Three Laws of Motion: Review Newton’s First Law: • Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force. Newton’s Second Law: • Force equals mass times acceleration (F = ma). Newton’s Third Law: • For every action there is an equal and opposite reaction.

  46. Bellwork: Friday 12/10/2010 Answer each question. Then, say which Law of Motion is being described. • A bat strikes a ball into the outfield.  If the action force is the bat hitting the ball, the reaction force is • the ball hitting the bat. • the ball flying into the air. • the ball hitting the ground. 2. Two dogs are tugging on a rope.  The rope is not moving because the dogs are pulling in • the same direction with equal force. • opposite directions with unequal force. • the same direction with unequal force. • opposite directions with equal force. 3rd Law 1st Law
