What are the forms of energy in physics?
Forms of Energy. Potential Energy – This is energy due to an object’s position. For example, a ball sitting on a table has potential energy with respect to the floor because gravity acts upon it. Mechanical Energy – Mechanical energy is the sum of the kinetic and potential energy of a body.
