What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a roller coaster at the top of a hill has maximum potential energy.

How does thermal energy transfer occur?

Back

Thermal energy transfer occurs through conduction, convection, and radiation.

Front

What is the difference between chemical energy and thermal energy?

Back

Chemical energy is stored in the bonds of chemical compounds, while thermal energy is the energy that comes from the temperature of matter.

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.
