What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another.

Front

What type of energy transformation occurs when a lamp is plugged in and functioning?

Back

Electrical energy is transformed into light energy.

Front

What does the law of conservation of energy state?

Back

The total energy in a closed system remains constant; it can change forms but cannot be created or destroyed.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds between atoms.

Front

What type of energy is found in a bicycle when it is moving?

Back

Mechanical energy.

Front

Give an example of energy transformation from electrical to mechanical to sound.

Back

A pencil sharpener plugged into an outlet transforms electrical energy into mechanical energy (motion) and then into sound energy.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.
