When it comes down again, that gravitational potential energy is converted back into kinetic energy. To calculate the kinetic energy of rolling motion, let us first consider the linear kinetic energy of a body with mass m which is moving with a velocity of v. Linear kinetic energy = ½ * m * v 2 This straightforward formula holds for all objects moving in a straight line and applies to the center of mass of the object. Explaining how energy is stored and transferred and how that relates to the movement and momentum of objects in motion involves understanding potential and kinetic energy. The equation for calculating kinetic energy is: kinetic energy = 1/2 mv 2, where m is the mass of the object (in kg) and v is the velocity of the object (in m/s). You would say that the object has a lot of energy. When falling, an object's PE due to gravity converts into KE and also heat due to air resistance. To easily remember this, think of kinetic and potential energy as opposites. Objects with total energy less than zero are bound; those with zero or greater are unbounded. kinetic energy. Java.
