Write an expression for the kinetic energy of an object.

The expression for the kinetic energy (KE) of an object is given by the formula:

KE = 1/2 x mass x velocity²

Where:
– KE is the kinetic energy measured in joules (J).
– Mass represents the mass of the object measured in kilograms (kg).
– Velocity is the speed of the object measured in meters per second (m/s).

This formula shows that the kinetic energy of an object is directly proportional to both its mass and the square of its velocity. As an object’s mass or velocity increases, its kinetic energy increases accordingly.
