Force and Motion Review

Front

What is force?

Back

A force is a push or pull on an object that can cause it to speed up, slow down, change direction, or stop.

Front

What happens when two people pull with the same amount of force?

Back

They will not move at all.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What direction does an object move when a force is applied?

Back

The object moves in the direction of the applied force.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

Which requires more force to move: a heavy object or a light object?

Back

A heavy object, like a bowling ball, requires more force to move.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is the effect of increasing the height of a ramp on a rolling car?

Back

Increasing the height of the ramp can increase the speed of the car as it rolls down.

Front

What is the role of the surface type in a rolling car experiment?

Back

The type of surface affects the amount of friction, which influences how far the car will travel.

Front

What is momentum?

Back

Momentum is the quantity of motion an object has, which depends on its mass and velocity.
