Laws of Motion

Newton's Laws of Motion

By Newton's second law, which says the acceleration of the body is directly proportional to the unbalanced net force and inversely proportional to body mass ratio is based on the force (F), mass (m) and acceleration (a). This is, of course, a wonderful relationship and a huge advantage.

F = ma

Knowing two quantities automatically gives you the third

Momentum

Momentum (p) is the moment of a body. A heavy body moves at a fast pace is hard to stop. A body of light at low speeds, on the other hand can be stopped easily. The momentum has to do with the mass and velocity.

p = mv

Often, the problems of physical force against before and after a collision. In this case, the total momentum of the bodies before the collision is taken equal to the amount of movement of the bodies after the collision. That is, the momentum is maintained.
