What is the formula for Kinetic Energy (KE)?

Kinetic energy (KE) is defined as the energy an object possesses due to its motion. The correct formula for calculating kinetic energy is given by the expression where KE is equal to one-half the mass of the object multiplied by the square of its velocity (1/2 × m × v²).

This formulation reflects the relationship between mass, velocity, and energy: as either the mass or the velocity of an object increases, its kinetic energy also increases. Notably, since the velocity is squared in the formula, a small increase in velocity results in a significant increase in kinetic energy.

Other options represent different physical concepts or calculations. The formula involving mass, gravitational acceleration, and height relates to gravitational potential energy, emphasizing elevation rather than motion. The expression involving mass, acceleration, and time outlines a different aspect of motion that does not directly correlate to energy. Lastly, the formula associated with force and distance represents the concept of work, not kinetic energy. Thus, the formula for kinetic energy effectively captures the essence of an object's motion and its impact on energy.
