2. Momentum Conservation Principle - The Physics Classroom
Two colliding object experience equal-strength forces that endure for equal-length times and result ini equal amounts of impulse and momentum change.
Two colliding object experience equal-strength forces that endure for equal-length times and result ini equal amounts of impulse and momentum change. As such, the momentum change of one object is equal (and oppositely-directed) tp the momentum change of the second object. If one object gains momentum, the second object loses momentum and the overall amount of momentum possessed by the two objects is the same before the collision as after the collision. We say that momentum is conserved.

Since the force of friction is opposite to the direction of travel, this acceleration causes the object to slow its forward motion, and eventually stop. The ...
Sir Isaac Newton put forth many important ideas in his famous book The Principia. His three laws of motion are the best known of these. The first law seems to be at odds with our everyday experience. Newton's first law states that any object at rest that is not acted upon by outside forces will remain at rest, and that any object in motion not acted upon by outside forces will continue its motion in a straight line at a constant velocity. If we roll a ball across the floor, we know that it will eventually come to a stop, seemingly contradicting the First Law. Our experience seems to agree with Aristotle's idea, that the "impetus" given to the ball is used up as it rolls. But Aristotle was wrong, as is our first impression of the ball's motion. The key is that the ball does experience an outside force, i.e., friction, as it rolls across the floor. This force causes the ball to decelerate (that is, it has a "negative" acceleration). According to Newton's second law an object will accelerate in the direction of the net force. Since the force of friction is opposite to the direction of travel, this acceleration causes the object to slow its forward motion, and eventually stop. The purpose of this laboratory exercise is to verify Newton's second law.
