- In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:KE = 1/2 mv2In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy.
