Lab 6: Conservation of Linear Momentum J 19 October 2017 General Physics I Laboratory PHY 2045L-L04
Introduction and Purpose: Newton’s third law of motion states that whenever body exerts force on another, the second body exerts a force on the first that is equal in magnitude and opposite in direction. The purpose of this experiment is to observe the principle of conservation of momentum.
