3.5 Newton’s laws of motion and momentum


The principle of conservation of momentum is that, 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. So, when two objects collide, the total momentum before and after the...

Newton developed three laws of motion: An object will remain at rest or continue to move at a constant velocity unless acted upon by a resultant force. The net (resultant) force acting on an object is directly proportional to the rate of change of its momentum, and is...
