  1. Identify your sources

  2. Inertia

  3. Don’t push it

  4. Action Reaction

  5. May the force be With you

  6. Force it!

  7. Identify your forces Inertia Don’t Push It Action Reaction May the force be with you Force it $100 $100 $100 $100 $100 $100 $200 $200 $200 $200 $200 $200 $300 $300 $300 $300 $300 $300 $400 $400 $400 $400 $400 $400 $500 $500 $500 $500 $500 $500

  8. This is the rate of change of velocity

  9. What is acceleration?

  10. An object is doing this when the distance between it and another object is changing

  11. What is in motion?

  12. This is Distance divided by Time.

  13. What is speed?

  14. A place or object • used as a comparison • point to tell whether an • object is moving is called • This.

  15. What is A reference point?

  16. This is the Definition of force

  17. What is: A push or a pull?

  18. A coin resting on a piece of cardboard is placed on a beaker as shown in the diagram. When the cardboard is rapidly removed, the coin drops into the beaker. This is called…

  19. What is inertia?

  20. A ball rolls through a hollow semicircular tube lying flat on a horizontal tabletop. This shows the motion the ball will take True or false. Fix it if false.

  21. What is false?

  22. Newton’s first Law states this

  23. What is Objects in motion, stay in motion, And objects at rest, stay at rest Until acted upon By an unbalanced force?

  24. This is the force that should stop you if the car stops short.

  25. What is The seat belt? NOT what is your face hitting the windshield? -5000 point

  26. This is the definition of inertia

  27. What is The tendency of an object to resist change In motion?

  28. A student pushes against a tree • with a force of 10 newtons (N). • The tree does not move. • This is the amount of force • exerted by the tree on the student.

  29. What is 10 N?

  30. The force of an object, with a certain mass accelerating at a certain rate, • can be determined by using the equation below. • force = mass X acceleration • Of the following obejcts, this object would have the greatest force: • a 5-kg object accelerating at 10 m/s2 • a 5-kg object accelerating at 20 m/s2 • a 20-kg object accelerating at 4 m/s2 • a 20-kg object accelerating at 3 m/s2

  31. What is • a 5-kg object • accelerating • at 20 m/s2?

  32. This law is why the boy Has to pull harder on The big rock to move it.

  33. What is Force = mass x acceleration So If the mass gets larger The force to pull it must be larger?

  34. This is what North and north poles do.

  35. What is Repel or push apart?

  36. Newton’s second Law relates mass, force, and acceleration In this mathematical formula.

  37. What is: F= m x a Or force equals mass times acceleration?

  38. Forces which are equal And opposite in direction move an object in this direction

  39. What is Balanced forces Don’t move objects ?

  40. A balloon can be used to Show Newton’s third Law in this diagram.

  41. What is: for every Action there Is an equal and Opposite reaction

  42. This is what happens when A skater pushes another skater

  43. What is: they both Go backwards with equal And opposite force?

  44. A student on a skateboard throws Something heavy. He moves in this direction.

  45. What is equal and opposite to the force of the throw?

  46. The reason the girl Fell in the Water is described by this law

  47. What is Newton’s third law: for Every action there is an Equal and opposite reaction?

  48. These are Two characteristics That affect the force of friction. .

  49. What are the surface Textures and how hard You press them together?
