Front

What is friction?

Back

A force that opposes motion between two surfaces that are in contact.

Front

What is mass?

Back

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

Front

How does mass affect force?

Back

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

Front

What is the relationship between speed and distance?

Back

Speed is calculated by dividing the distance traveled by the time taken.

Front

What happens to a wagon going down a hill?

Back

It speeds up due to the force of gravity acting on it.

Front

Can speed be measured if an object is moving backward?

Back

Yes, speed can be measured regardless of the direction of motion.
