Unit 8: Forces Test Review Game

Name the force that slows down an object or keeps it from moving.

Name the force that slows down an object or keeps it from moving. friction

A) Which object would require more force to make it move, a semi-truck or a toy car? b) Why?

because it has more mass. Which object would require more force to make it move, a semi-truck or a toy car? Why? Semi-truck because it has more mass.

A student sets up an experiment to determine how friction affects the motion of a toy car. How can the student change the amount of friction in each trial?

Place the toy car on different surfaces. A student sets up an experiment to determine how friction affects the motion of a toy car. How can the student change the amount of friction in each trial? Place the toy car on different surfaces.

If the same amount of force is applied to several objects that have different masses, which object will have the greatest change in motion?

The object with the smallest mass If the same amount of force is applied to several objects that have different masses, which object will have the greatest change in motion? The object with the smallest mass

Describe the motion of an object when the forces on the object are balanced.

it will move in a straight line at a constant speed. Describe the motion of an object when the forces on the object are balanced. It will not move OR it will move in a straight line at a constant speed.

The heavier the ball, the less force it will exert on the car. Balls are rolled down a ramp and push a toy car. Which of the following is true? The heavier the ball, the less force it will exert on the car. The lighter the ball, the farther the car will roll. The heavier the ball, the more force it will exert on the car. The lighter the car, the harder it is to move.
