Which of the following best describes kinetic energy?

Kinetic energy is defined as the energy that an object possesses due to its motion. This concept stems from the idea that any object in motion—whether it's a moving car, a flying ball, or even particles in a gas—has kinetic energy proportional to its mass and the square of its velocity. The mathematical expression for kinetic energy is given by the formula ( KE = \frac{1}{2}mv^2 ), where ( m ) represents the mass of the object and ( v ) is its velocity.

The other options relate to different forms of energy, which do not accurately describe kinetic energy. For instance, energy associated with position refers to potential energy, which depends on an object's position within a gravitational or electric field. Energy stored in chemical bonds pertains to potential energy found in molecular bonds, often released during chemical reactions. Finally, energy released during an earthquake typically involves seismic energy, which is a complex interaction of potential and kinetic energy transformation but does not directly define kinetic energy itself.
