Energy resources & forms, Potential energy, Kinetic energy

Mechanical energy is the sum of potential and kinetic energies of the body. The moving object keeps its mechanical energy during motion constant because mechanical energy is the sum of potential and kinetic energies of the object and the decrease in the kinetic energy of the moving object equals the increase in its potential energy and vice versa.


Some countries try to use the wind energy and solar energy as resources of energy because they are cheap and clean resources of energy as they do not pollute the environment, The weight of an object is different from its mass because the object's weight = object's mass × acceleration due to gravity.


No change in the potential energy when the object moves horizontally because its height doesn't change as the potential energy is directly proportional to the height of the object from the ground.

Harnessing the energy sources that we actually have right now is very impressive. This is impressive as this is showing human creativity. - Phillip Elden
