Question

what is kinetic energy? what does kinetic energy depend on?

Explanation:

Kinetic energy is the energy an object possesses due to its motion. It depends on two factors: the mass of the object and its velocity. The formula for kinetic energy is $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity. Mass is a measure of the amount of matter in an object, and velocity is the speed of the object in a given direction. The greater the mass or velocity of an object, the more kinetic energy it has.

Answer:

Kinetic energy is the energy of motion. It depends on an object's mass and velocity.
