What is the formula for kinetic energy, which is represented by the equation E 1/2mv2, and how is it used in physics?

The formula for kinetic energy is E 1/2mv2, where E represents kinetic energy, m is the mass of an object, and v is its velocity. This formula is used in physics to calculate the energy of an object in motion. It helps determine how much energy an object has due to its movement, which is important in understanding the behavior of objects in motion and their interactions with other objects.
