What is energy in physics class 7?
unit of energy is joule (J). Kinetic energy of a body is the energy possessed by it due to its motion. ... According to the conservation of mechanical energy, if friction is neglected, the total sum of potential energy and kinetic energy remains constant.
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved
