Front

Give an example of a situation that does not involve energy transfer through a collision.

Back

A baseball flying through the air is not an example of a collision causing energy transfer.

Front

Define a collision in physics.

Back

A collision is when two or more objects crash into each other with a force.

Front

How does friction affect energy during motion?

Back

Friction converts some kinetic energy into heat, reducing the total kinetic energy.
