You do no net work when you walk at a constant speed . Why do you get tired?
Is the force of a tennis racket acting on a tennis ball a conservative force?
A vase falls to the floor and shatters. Is momentum conserved in the collision?What objects needto be taken into account in describing the conservation of momentum?
Please help, I'm studying for an exam and need to understand the concepts in these questions. Thankz
