What is kinetic energy and how is it represented by the formula?

Kinetic energy, like any energy, shows what kind of work the body can do. If a body has a lot of kinetic energy, then this body can do a lot of work. The unit of measurement for kinetic energy is joule (J).
The kinetic energy Ek is called the energy of motion, it is determined by the formula: Ek = m * V ^ 2/2, where m is the mass of the body, V is the speed of movement.
A body with a mass of 1 kg, which moves at a speed of 1 m / s, has a kinetic energy of 1J.
