How much kinetic energy is in his throw

WebApr 7, 2024 · A two-kilogram mass (something weighing 4.4 pounds on Earth) moving at a speed of one metre per second (slightly more than two miles per hour) has a kinetic energy of one joule. In the centimetre-gram-second system the unit of energy is the erg, 10 −7 joule, equivalent to the kinetic energy of a mosquito in flight. WebAug 13, 2024 · Each also gain kinetic energy but the ball will gain much more kinetic energy than the Earth because the mass of the ball is so much smaller than the mass of the Earth. If the ball and Earth stick together after they collide then the system has no kinetic energy.
