The best statement to describe Gabriel’s measurement is “They will both be recorded in joules.” Performing an experiment in measuring the energy and work being done by a ball rolling down a hill is not an easy task it needs much effort and time to conduct this kind of experiment. Work can transfer energy between objects and it can cause a change in the form of energy. When work is being done the possibility of this is the energy will transfer. Work is the measure of the energy when the object is moving by an external force. Energy is the capacity of the object to do the work. It may exist in kinetic, thermal, potential, chemical and other various forms.
