Presentation Transcript
Question 1 - 10
• The slope of a position versus time graph represents this.
• What is speed?
Question 1 - 20
• An object is dropped from rest and falls downward for 5 seconds. What is its average speed?
• What is 24.5 m/s?
Question 1 - 30
• Acceleration of an object must be caused by a force that is this.
• What is not zero?
Question 1 - 40
• 2 km equals this many centimeters.
• What are 200,000?
Question 1 - 50
• A unit of acceleration.
• What are m/sec2? (any speed/time)
Question 2 - 10
• The term used to describe an object speeding up.
• What is acceleration?
Question 2 - 20
• The term that refers to an object slowing down.
• What is deceleration?
Question 2 - 30
• This may occur when an object is accelerated.
• What is a change in speed, a change in direction or both?
Question 2 - 40
• Newton’s first law is also known as this.
• What is the Law of Inertia?
Question 2 - 50
• Newton’s Second Law Formula
• What is F=ma
Question 3 - 10
• Two horizontal forces are applied to a box, 5 N to the right and 12 N to the left. This is the motion of the box.
• What is 7N to the left.
Question 3 - 20
• This is the acceleration due to gravity, numerically.
• What is 9.8 m/s2?
Question 3 - 30
• When an object is accelerating due to the force of gravity with no other forces acting on it.
• What is free fall?
Question 3 - 40
• The inertial of an object is related to this.
• What is mass?
Question 3 - 50
• Gwen rides her bicycle 2.4 km up a steep hill in 8 minutes. This is her speed in km/min.
• What is 0.3 km/min?
Question 4 - 10
• If you know the distance traveled and the amount of time it took, you can calculate speed using this equation.
• What is distance divided by time?
Question 4 - 20

This is how many centimeters tall a person who is 1.65 meters is.

• What is 165 cm?
Question 4 - 30
• The newton is defined as this.
• What is the force that can give a 1 kg mass an acceleration of 1 m/s2?
Question 4 - 40
• The amount of change in the speed of an object divided by the amount of time it took to change the speed.
• What is acceleration?
Question 4 - 50
• When you throw a ball up in the air, the point where it stops and changes its direction to fall back down, this is zero.
• What is velocity/speed?
Question 5 - 10
• This is the formula to calculate free fall distance.
• What is d=1/2gt2 or d=vavgt ?
Question 5 - 20
• An apple falls from the top branch of a tree and lands 1 second later. This is the height of the branch.
