The forms of energy are light, heat, chemical, and motion. There are many forms of energy, but they can all be put into two categories: Potential and Kinetic.
Potential energy Kinetic energy
Potential Energy Potential energy- Potential energy is energy which results from position or configuration. An object may have the capacity for doing work as a result of its position in a gravitational field (gravitational potential energy), an electric field (electric potential energy), or a magnetic field (magnetic potential energy). It may have elastic potential energy as a result of a stretched spring or other elastic deformation.
There are 2 types of energy sources: nonrenewable and renewable. Energy sources are considered nonrenewable if they cannot be replenished (made again) in a short period of time. On the other hand, renewable energy sources such as solar and wind can be replenished naturally in a short period of time.
