Front

How does pushing relate to motion?

Back

Pushing an object applies a force that can change its motion, making it move in the direction of the push.

Front

What is the relationship between mass and density?

Back

Density is calculated by dividing mass by volume; higher mass with the same volume results in higher density.

Front

What is an example of an object moving in the opposite direction?

Back

A car moving east while another car moves west is an example of opposite direction.
