Physics kinetic energy unit
WebbThe Kinetic Energy of a body depends upon factors such as the body’s mass and velocity attained by the body due to the force applied to it. Joule is the SI metric unit for Kinetic Energy. 1 Joule can be defined as the energy stored in a body of mass 0.5 kg moving at a velocity of 1 m/s. Similarly, the CGS unit of kinetic energy is erg. WebbSince heat, like work, transfers energy, it has the SI unit of joule (J). Atoms and molecules are constantly in motion, bouncing off one another in random directions. Recall that kinetic energy is the energy of motion, and that it increases in proportion to velocity squared.
