What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a rock at the top of a hill has gravitational potential energy.

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

What is renewable energy?

Back

Renewable energy is energy that comes from sources that can be replenished naturally, such as solar, wind, and hydroelectric power.

Front

What is non-renewable energy?

Back

Non-renewable energy comes from sources that cannot be replenished in a short period of time, such as fossil fuels like coal, oil, and natural gas.
