What is Energy?
The energy is a measure of how long we can sustain the output of power, or how much work we can do. There are two kinds of energy, potential and kinetic.
Potential energy is the energy waiting to be converted into power. Gasoline in a fuel tank is an example.
Kinetic energy is the energy a body possesses because it is in motion. The more the object weighs and the faster it is moving, the more kinetic energy it has.
The formula for kinetic energy is:
Kinetic Energy = m * v^{2} / 2, where "m" is the mass and "v" is the velocity.
What is Work?
The work is the application of a force over a distance. Work is equal to the product of the force and the distance through which it produces movement.
