Lab 6Conservation of Linear Momentum
Introduction and Purpose of Experiment: In this experiment, we are testing Conservation of Linear Momentum. Newtown’s third law of motion states that when one body uses force ⃗F=d⃗pdt,on another, the second body uses a force on the first that is equal in magnitude and opposite in direction. When this occurs, the impulse ∆⃗pdelivered to each of the two bodies in each time interval ∆tare equal and opposite. The total momentum of the system reproduced by the formula:∆⃗ptotal=m1⃗v1+m2⃗v2.We know that if the vector sum of all external forces is zero, the momentum change of one body is equal and opposite to that of the first, so the total momentum remains a constant.
