Speed, Velocity, and Acceleration
... • Before landing, the ball went through several changes in motion. It sped up in the pitcher’s hand, and lost speed as it traveled toward the batter. The ball stopped when it hit the bat, changed direction, sped up again, and eventually slowed down. Most examples of motion involve similar changes. I ...

6. APPLICATION OF NEWTON`S LAWS Concepts: 6.1 FRICTION
... Static friction is usually stronger than kinetic. Example. You are about to move a heavy box which is just sitting on the floor. Velocity =0. Kinetic friction = 0. Static friction is zero because you haven’t started pushing on it. As you push on it, you feel the box push back with equal force. The b ...
