Conservation of energy formula questions: 1) an astronaut on the moon picks up a rock, and holds it out at that moment, the rock is at rest, and has 500 j of gravitational potential energy. Questions and answers about renewable energy what is renewable energy renewable energy is made from resources that can be renewed by mother nature: wind, . Energy transformations and conservation of energy energy of system and surroundings definition of kinetic energy, with equation (k = 1/2mv 2) definition of work done by a constant force, with equation (w applied = f x δ x).
Conservation of energy theorem nothing can be destroyed or created in the universe like energy suppose that a ball falls from height of 2m, it has only potential energy at the beginning, however, as it falls it gains kinetic energy and its velocity increases. We pick the best questions and expert answers from our live debate on cutting energy bills and carbon emissions. Conservation of energy conservation of mechanical energy problems relate speed of an object at and there are a variety of question types in thermal energy .
