SUMMARY
The change in kinetic energy is defined as the difference between the final and initial kinetic energy of an object. The expression for kinetic energy (KE) is given by the formula KE = 0.5 * m * v², where m is the mass and v is the velocity of the object. To change the kinetic energy, either the mass (m) or the velocity (v) must change, with velocity being the primary variable that affects kinetic energy when mass remains constant.
