A 15kg object falls a distance of 5.0 meters. How much work does gravity do on the object during this motion? Use the work-energy principle (from chapter 6- NO POTENTIAL ENERGY) to determine the speed of the object just as it reaches the ground. Assume there is no air resistance and the object starts from rest.

An object can possess kinetic energy, the energy of motion, and/or potential energy, the energy of position. Energy can be transferred in many ways, one of which is in the form of work. Work, w, is the energy transferred when an object is caused to move a distance, d, against a force, F. Mathematically, we would write this as w=Fd Force is the product of mass, m, and acceleration, a: F=ma When the acceleration is due to gravity, the symbol...
