What is the difference between energy, force and momentum?
In: Physics
Objects have mass.
Objects can move (that is, objects have velocity).
An objects mass times its velocity is its momentum. That is, the heavy it is and/or the faster it is moving, the higher its momentum.
Force is how objects change their momentum or velocity. Newton’s second law says the rate in which an objects momentum changes is equal to the force acting on it.
You can also think of force as what is required to accelerate any object of a given mass by a certain amount.
There are a lot of forms or depiction of energy, but in the context of motion, energy is basically applying a force to an object over a certain amount of distance.
In short:
Move an object = momentum
Accelerate an object or change its momentum = force
Apply a force over a certain distance = energy
