Physical Science Review

Front

What effect does more friction have on the speed of an object?

Back

More friction decreases the speed of an object.

Front

What is used to determine an object's motion?

Back

The distance an object moves and the time it takes to move.

Front

What is an insulator?

Back

An insulator does NOT allow heat to travel through easily.

Front

What happens to an object when the temperature decreases?

Back

The object contracts.

Front

How does mass affect an object's motion?

Back

An object in motion with more mass is harder to stop.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is the relationship between force and motion?

Back

Force causes an object to move or change its motion.

Front

What is the definition of mass?

Back

Mass is the amount of matter in an object.

Front

What happens to the speed of an object when it is pushed?

Back

The speed of the object increases if the force is strong enough.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in size of an object when its temperature increases.
