Front

A horse that is accelerating is ___________.

Back

slowing down

Front

How does the energy change when work is done on an object?

Back

The object could move or change.

Front

The amount of kinetic energy an object has is related to its mass and speed/velocity. True or False?

Back

True

Front

The more friction between colliding objects, the ___________ heat produced during a collision.

Back

Front

What is kinetic energy?

Back

the energy of a moving object

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What is potential energy?

Back

Energy stored in an object due to its position or structure.

Front

What happens to energy when an object falls?

Back

Potential energy is converted to kinetic energy.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity).
