If Kinetic Energy KE is constant. Substituting for mv in the above equation we get-. This short video shows you why with some animated algebra.
The work that is done on an object is related to the change in its kinetic energy.
The formula for kinetic energy can be obtained by the method of calculus. K 12 Iw 2. If kinetic energy is the energy of motion then naturally the kinetic energy of an object at rest should be zero. Kinetic Energy Formula Rotational The rotational kinetic energy equation goes like this.
