Reference Point
What question were they most likely trying to answer?
Does the mass of a car affect the change in motion?
Does the force on a car affect the change in motion?
Does the distance the car travels affect the time?
Does the mass of a car affect the distance the car travels?
Which of the following best explains the motion of the car represented in section “D” of the graph?
The car is stopped in section “D”.
The car is going faster than it was in section “B”.
The car is moving on level ground in section “D”.
The car is higher than it was in section “B”.
Which car won the race?
Car 1
Car 2
Car 3
Car 4
What would most likely happen to the motion of the box if you poured oil on the ramp?
It will slow the box because the force of friction will be increased.
It will speed up the box because the force of friction will be increased.
It will slow the box because the force of friction will be reduced.
It will speed up the box because the force of friction will be reduced.
Which of the following best explains what magnet “B” will do if it is free to move?
The force of gravity will pull it to the left.
The force of gravity will push it to the right.
The magnetic force will pull it to the left.
The magnetic force will push it to the right.
What was the most likely trying to model?
The speed of a car.
The forces acting on a car.
The distance a car might move.
The things that change the size of a car
If an unbalanced force acts on an object at rest, the object will move in the direction of the force. Which of the following best models an object with unbalanced forces acting on it?
A student wishes to design an investigation to determine the effect of changing the mass of an object when an unbalanced force is applied to the object. What should she use as the independent variable in her investigation?
time
force
mass
speed
Which hypothesis will most likely be supported by the results of the investigation?
When a balanced force is applied the block with the greatest mass will move fastest.
When an unbalanced force is applied the block with the least mass will move fastest.
When a balanced force is applied the speed of the object will not change.
When an unbalanced force is applied the speed of the object will not change.
The arrows in the diagrams below represent the size and direction of the forces that are acting on a cart. Different forces were applied to carts. The mass of each cart is the same. If the carts started at rest, which one would speed up the most in a direction to the right of the page?
(a) Mass = More Acceleration
What is acceleration? Pick all that apply.
Speeding up
Slowing down
Changing direction
Constant Speed
Explain why this picture demonstrates Newton's 1st Law of Motion.
An object at rest remains at rest, and an object in motion remains in motion unless acted upon by an unbalanced force.
1st Law of Inertia
2nd Law of Force, Mass, Acceleration
An objects acceleration depends on the objects mass and the amount of force applied.
1st Law
2nd Law
Force = _________ x _________
(a)

1,300 N
900 N
94 N
