Equate potential energy and kinetic energy; i. kinetic energy mass and speed activity The following equation is used to represent the kinetic energy (KE) of an object: where m = mass of object v = speed of object In physics, the kinetic energy of an object is the energy that it possesses due to its motion. In this activity, students do not construct their own graphs. When temperature increases, the kinetic energy of the gas molecules also increases; conversely, when the temperature decreases, the gas molecules' kinetic energy also decreases. Relativistic kinetic energy is equal to the increase in the mass of a particle over that which it has at rest multiplied by the square of the speed of light. A car traveling down the road has less kinetic energy than a semi-truck traveling at the same speed because the car's mass is much less than the truck's.
