Front

What is kinetic energy?

Back

The energy that an object has because it is moving.

Front

What is energy?

Back

The ability to make things move or change.

Front

What happens to potential energy (PE) and kinetic energy (KE) when an object falls?

Back

The potential energy decreases while kinetic energy increases.

Front

What is the sequence of energy transformations in a hairdryer?

Back

Electrical energy transforms into thermal energy and sound energy.

Front

True or False: Nothing creates energy; it must be transferred from something else.

Back

True.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

Give an example of kinetic energy.

Back

A moving car or a running athlete.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What type of energy is associated with the position of an object?

Back

Potential energy.

Front

What is an example of energy transformation?

Back
