Centripetal Acceleration and Centripetal Force
... Centripetal Acceleration • Centripetal means center-seeking. • Centripetal acceleration is always directed toward the center of the circle of motion. • It is this centripetal acceleration that is responsible for the change in the direction of the velocity; the magnitude of the velocity remains cons ...

... Troublesome HW4 questions 16. I push on a refrigerator (horizontally), but it does not move. Explain how this can be. (A) the downward force of gravity on the fridge is larger than the force that I can exert on the fridge. (B) the frictional force of the floor on the fridge exactly cancels the forc ...

... Despite a very strong wind, a tennis player manages to hit a tennis ball with her racquet so that the ball passes over the net and lands in her opponent’s court. Consider the following forces: 1. A downward force of gravity, 2. A force by the hit, and 3. A force exerted by the air. Which of the abov ...
