Question

what is kinetic energy (ke)?

Explanation:

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity, with the formula $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity.

Answer:

Kinetic energy is the energy of motion, calculated by $KE = \frac{1}{2}mv^{2}$ where $m$ is the mass of the object and $v$ is its velocity.
