episode 19: The APsolute RecAP: Physics 1 Edition - Momentum - Center of Mass
Episode 19 explores the concept of center of mass, and specifically how the momentum of the center of mass is affected during collisions of the objects in the system. We start by observing a child and parent playing on a seesaw at the park (0:41). The center of mass calculation is presented, and an example provided (1:22). The action is quickly relocated to an ice rink and the collision of two ice hockey players to see that the momentum of the center of mass is conserved (4:23).
The Question of the Day asks: (6:17)
Two friends attempt to balance on a paddleboard of length L. One friend is 3 times as massive. If the heavier friend stands on one end of the board, where should the lighter friend stand to maintain balance?
