Kinetic energy is the energy an object possesses due to its motion. It’s directly proportional to the object’s mass and the square of its velocity. The formula for kinetic energy is KE = 1/2 * mv^2, where KE is kinetic energy, m is mass, and v is velocity.
Expression for kinetic energy: Let a body of mass m moves with a velocity v. Let a constant forc F be applied on it so that it comes to rest after travelling a distance S
