Forces 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 mass?

Back

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

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is friction?

Back

A force that opposes the motion of an object, often caused by contact with another surface.

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 speed?

Back

The distance an object travels in a certain amount of time.

Front

What is direction in motion?

Back

The path that an object follows as it moves, which can be described using terms like up, down, left, or right.

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

Front

What happens to a moving object when friction acts on it?

Back

It slows down and eventually stops.

Front

What is a slope?

Back

An inclined surface that can affect the motion of objects, such as a hill.
