If i wanted to increase the gravitational potential energy of a ball do I always have to apply a force times a distance? In this case the force would be the weight of the ball and the distance would be the height. What if I kicked the ball upwards? I wouldn't be applying a force times a distance , but I would be giving it momentum. So my question is, I don't always have to apply a force times a distance to increase the GPE or KE of an object do I?
