What factors determine the kinetic energy of an object?

Back

The kinetic energy of an object depends on its mass and speed.

Front

What is Energy Transformation?

Back

Energy Transformation is the process of changing energy from one form to another, such as electricity being converted into heat in a microwave.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only change forms.
