Force and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What is friction?

Back

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

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be a change in speed or direction.

Front

What is a ramp?

Back

An inclined surface that connects a lower level to a higher level, used to help move objects up or down.

Front

What is a toy car?

Back

A small model of a car that is often used for play and can demonstrate principles of force and motion.

Front

What is the effect of height on motion?

Back

Increasing the height of a ramp can increase the distance a rolling object travels due to greater gravitational potential energy.

Front

What is a wheeled cart?

Back

A platform with wheels that makes it easier to move heavy objects by reducing friction.
