Question: how much energy does it take to move an object?
Answer: The amount of kinetic energy gained depends on the mass and the speed of the object. Find the kinetic energy of a 10 kg mass which is moving at 20 m/s. Ek = ½ x 10 kg x (20 m/s)2 = 2000 Joules When moving objects be stopped, all their kinetic energy must be transformed into another form of energy.
