Document Summary
An astronaut drops a golf ball that is initially at rest from a cliff on the surface of the moon. The ball falls freely under the influence of gravity. The ball will gain an equal amount of momentum during each second. During the filming of a movie, a stunt person jumps from the roof of a tall building, but no injury occurs because the person lands on a large, air-filled bag. The bag increases the amount of time during which the momentum is changing and reduces the average force on the person. A sports car of mass m has the same kinetic energy as an suv with a mass 3m as each is driven along the same road. The suv has about 73% greater momentum than the car. The asteroid exerts the same amount of force on the planet as the planet exerts on the asteroid. Three events are observed at a baseball game:
