Back

Chemical energy is transformed into mechanical energy during digestion.

Front

What energy transformation occurs in a microwave oven?

Back

Electrical energy is transformed into thermal energy and light energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, often highest at the top of a hill or roller coaster.

Front

At which position does a roller coaster cart have the most gravitational potential energy?

Back

The roller coaster cart has the most gravitational potential energy at the highest point, often labeled as position W.

What energy transformation occurs when a lamp is turned on?

Back

Electrical energy is transformed into thermal energy, light energy, and sometimes sound energy.

Front

Which type of energy is NOT produced by a lamp?

Back

A lamp does not produce chemical energy.

Front

What type of energy transformation occurs in an electric hot plate?

Back

Electrical energy is transformed into thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, related to its motion and position.
