Question

Quizplus · Accepted Answer

Momentum is a vector quantity, meaning it has both magnitude and direction. When two objects of equal mass move at the same speed but in opposite directions, their momenta are equal in magnitude but opposite in direction. Upon collision, these momenta cancel each other out, resulting in a total momentum of zero.
