Mr. Talboo – Physics Circular Motion Sample Problems SAMPLE A Billy Bocephus thought of a plan to catch a squirrel for dinner. He ties a 1.5-kg rock to a string so that he can swing it in a circle above his head. The string is 2.2 meters long and while swinging, the rock makes 3 revolutions each second. (a) Calculate the period of the rock.

Acceleration and Circular Motion When an object moves in a circular orbit, the direction of the velocity changes and the speed may change as well. For circular motion, the acceleration will always have a non-positive radial component (a r) due to the change in direction of velocity, (it may be zero at the instant the velocity is zero).

A circular loop would cause a jolting change in acceleration at entry, a disadvantage discovered long ago in railroad curve design. With a small radius of curvature at the top, the centripetal acceleration can more easily be kept greater than g so that the passengers do not lose contact with their seats nor do they need seat belts to keep them .
