24. 24. What is conservation of momentum? The conservation of momentum is the fundamental law that objects acting in a closed system will maintain momentum through collisions with other objects in the system. Or When t wo objects collide the starting momentum of the objects will be the same as the finishing momentum of the objects.Thursday, April 14, 2011
25. 25. How do we represent conservation of momentum? We represent conservation of momentum of t wo objects with the equation... p1i + p2i = p1f + p2f Where, p1i = the initial momentum of object 1 p2i = the initial momentum of object 2 p1f = the final momentum of object 1 p2f = the final momentum of object 2 The Equation can also be written as... (m1 x v1i) +(m2 x v2i) = (m1 x v1f) + (m2 x v2f)Thursday, April 14, 2011
