The kinetic energy (KE) of an object with mass (m) and velocity (v) is calculated using the formula: KE = 0.5 × m × v². In this equation, 0.5 represents the constant factor and is included to account for the relationship between kinetic energy and velocity squared. The mass of the object is multiplied by the square of its velocity, and the result is divided by 2. This formula demonstrates that kinetic energy increases with both mass and the square of velocity. It quantifies the energy associated with an object’s motion, providing a useful tool for understanding and analyzing dynamic systems.
