What type of energy is transferred to thermal energy?

Back

Electrical energy is transferred to thermal energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the law of conservation of energy?

Back

Energy can never be created or destroyed; it can only be transformed from one form to another.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, such as a moving car.
