Newton`s Second Law
... • The momentum of an object doesn’t change unless its mass, velocity, or both change. • Momentum, however, can be transferred from one object to another. • The law of conservation of momentum states that if a group of objects exerts forces only on each other, their total momentum doesn’t change. ...

... indeed acts. 19. If there were no force acting on the ball, it would continue in motion without slowing. But air drag does act, along with slight friction with the lane, and the ball slows. This doesn’t violate the law of inertia because external forces indeed act. 20. The maximum resultant occurs w ...
