WebThe kinetic energy of an object depends on its mass and velocity (v). The formula for kinetic energy is: KE=½ mv 2. When we drop the object, the force of gravity starts its work, and it provides kinetic energy to the object. As only the kinetic energy is increasing, there is a change in the value of quantity ½ mv 2. WebApr 10, 2024 · Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. The formula to calculate Kinetic energy is: KE = browns worcester hotel
