Newton's Laws of Motion and Momentum

Newton's First Law of Motion

A body will remain at rest or continue to move with constant velocity unless acted upon by a resultant force.

1 of 8

Newton's Second Law of Motion

The rate of change of momentum of an object is directy proportional to the resultant force and takes place in the direction of the force.

2 of 8

Newton's Third Law of Motion

When two objects interact, each exerts an equal but opposite force on the other during the interaction.

3 of 8

Closed System

An isolated system that has no interaction with its surroundings.

4 of 8

The Principle of Conservation of Momentum

For a system of interacting objects, the total momentum in a specified direction remains constant, as long as no external forces act on the system.

5 of 8

Inelastic Collision

A collision in which kinetic energy is lost. Total energy is conserved.

6 of 8

Perfectly Elastic Collision

A collision in which no kinetic energy is lost.

7 of 8

Impulse

The area under a force - time graph. The product of force and the time for which the force acts equal to the change in momentum.
