Front

An energy transformation ____________.

Back

is a change from one form of energy to another.

Front

A light bulb converts which forms of energy? (Remember, order is important)

Back

electrical energy to electromagnetic energy.

Front

Which is a continuous transformation between potential and kinetic energy?

Back

a pendulum swinging.

Front

Law of conservation of energy states _______________________

Back

that energy cannot be created or destroyed.

Front

A pole-vaulter's next energy transformation from kinetic energy is to which form of energy?

Back

Elastic potential energy.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is potential energy?

Back

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

Front

Give an example of energy transformation in a battery-powered toy.

Back

Chemical energy in the battery transforms to kinetic energy as the toy moves.

Front

What happens to energy in a closed system?

Back

Energy is conserved; it cannot be created or destroyed.

Front

What is mechanical energy?

Back

The sum of potential and kinetic energy in an object.
