Forms of Energy

-Chemical energy is energy stored in fuel. This energy is released when chemical reactions take place.

-Kinetic energy is the energy of a moving object.

-Gravitational potential energy is the energy of an object due to its position.

-Elastic potential energy is the energy stored in a springy object when we stretch or squash it.

-Electrical energy is energy transferred by an electric current

-Energy can easily change from one form to another. Energy is never created or destroyed, only transformed.

-When an object falls it gains kinetic energy because it speeds up as it falls, so it's gravitational potential energy is transferred to kinetic energy.As its gravitational potential energy decreases, its kinetic…
