Which of the following is an example of kinetic energy?

Kinetic energy is defined as the energy that an object possesses due to its motion. It depends on both the mass of the object and its velocity, with the formula for kinetic energy being ( KE = \frac{1}{2} mv^2 ), where ( m ) represents mass and ( v ) represents velocity.

In this context, a moving car exemplifies kinetic energy because it is actively in motion. The speed of the car in relation to its mass contributes to the total kinetic energy it possesses. The energy in the moving car is being actively converted as it moves, showcasing the principles of kinetic energy in a straightforward way.

The other options represent forms of potential energy or stored energy. A compressed spring stores potential energy due to the deformation of the spring, a drawn bow stores energy in the form of potential energy due to its tension, and a stored battery contains chemical energy that can be transformed into other forms of energy, such as electrical energy when used. None of these examples involve motion in the way that a moving car does.
