Which formula is used to calculate kinetic energy?

The formula used to calculate kinetic energy is expressed as KE = 1/2 mv². In this formula, "KE" stands for kinetic energy, "m" is the mass of the object, and "v" represents the velocity of the object.

Kinetic energy is the energy that an object possesses due to its motion. The relationship between kinetic energy and mass shows that as the mass increases, the kinetic energy also increases, assuming the velocity remains constant.

The squared term for velocity (v²) indicates that the kinetic energy increases significantly with increases in speed; for example, if an object's velocity doubles, its kinetic energy increases by a factor of four, reflecting that kinetic energy is dependent on the speed of the object in a nonlinear fashion.

This formula highlights the essential aspects of motion and energy and is fundamental in physics, helping to describe how kinetic energy behaves in different scenarios involving mass and velocity.
