Dynamics: Energy and Power of a Particle



Energy

When a force is used to move a particle a certain amount of work or energy is required to move that particle a certain distance. In other words to calculate the energy that was expended in moving a particle, energy would be a function of force times distance. Refer to equation one.

Fundemental energy equation (1)

F = force

Δs = change in distance

U1-2 = change in energy

There are two types of energy that need to be considered when dealing with motion. Those are potential energy and kinetic energy.
