Energy in the gravitational potential energy store = ? The faster an object is travelling, the more energy there is in the kinetic energy store of the object. How fast the object is moving is its ...

As the book gets faster it gains more kinetic energy and loses more potential energy. Just before it hits the floor all the gravitational potential energy has been converted to kinetic energy.

One exciting area of potential application for ... to excite core electrons into unoccupied energy levels and then measured the distribution of kinetic energies of the electrons emitted as a ...
