If its true that energy isn't lost, its just transferred, where did the energy go from a falling object that hits the floor and stays there? It started with the most gravitational potential energy, a second before it lands it is converted to kinetic energy, and the kinetic is at the peak. But after it fell and stopped, where is all the energy?
Also, it is said you can't create energy. But when an object is at rest on the floor it has no energy, and after being picked up it has energy.
I know these are basic questions, but I can't get to the bottom of this.
