  • Slow the object down
  • Change the object's direction
Q.9
Imagine Mr. Gomez spinning a yo-yo in a circular motion with a constant speed. Would the yo-yo have an acceleration during its motion?
  • Yes; the displacement is changing, resulting in a changing acceleration
  • No; objects at a constant speed always have zero acceleration
  • No; acceleration does not apply to centripetal (circular) motion
  • Yes; the direction is constantly changing, which changes the acceleration
