When the ball hits the ground, it has fallen the distanceH. Now its kinetic energy equals the potential energy at the start of its fall. After falling the distanceH, the kinetic energy equals the potential energy of Mass of the ball times the acceleration due to gravity times the height,H...
If a rigid body moves under gravity, its total energyEis the sum of the kinetic and potential energies. As an example, let us consider the motion of a sphere on an inclined plane (Fig. 26). The potential energy of the sphere isMgz, whereMis the mass of the sphere andzthe height of ...
The Law of Conservation of Energy states that energy cannot be created or destroyed. In other words, the total energy of a system remains constant. This is an

Energy strides over the conceptual arena of physics like a colossus. It can assume a multitude of forms. The energy possessed by virtue of speed is called the kinetic energy. The energy due to the position of an object in an external field is called the potential ener...
Work-Energy Theorem The total work done on an object equals the change in the object’s kinetic energy, provided there is no change in any other form of energy (for example, gravitational potential energy). We can summarize the relationship involving the total work and the kinetic energy as ...
atomic energy, nuclear energy - the energy released by a nuclear reaction binding energy, separation energy - the energy required to separate particles from a molecule or atom or nucleus; equals the mass defect chemical energy - that part of the energy in a substance that can be released by ...

If you drop a 13.0-kg ball from a height of 30 m (neglect friction), how many joules of potential energy does it have at the moment before dropping it? A 0.600-kg particle has a speed of 2.00 m/s at point A and kinetic energy of 7.50 ...
