Which of the following best describes "kinetic energy" in biomechanics?

Kinetic energy in biomechanics refers specifically to the energy an object possesses due to its motion. This energy is defined by the formula ( KE = \frac{1}{2}mv^2 ), where ( m ) is the mass of the object and ( v ) is its velocity. Essentially, the faster an object moves, and the more massive it is, the greater its kinetic energy will be.

In the context of biomechanics, understanding kinetic energy is crucial for analyzing movements, whether it's a runner sprinting or an athlete performing a dynamic skill. It helps in assessing the forces and impacts involved in these activities. Therefore, recognizing that kinetic energy is fundamentally linked to motion gives a clear insight into its role in both human performance and mechanical systems within biomechanics.
