For each of the following situations involving circular motion, identify what force provides the centripetal acceleration. Draw a force diagram showing all the forces on the object. (a) The earth, rotating around the sun (b) A bicycle being ridden around a corner on a banked velodrome
For each of the following situations involving circular motion, identify what force provides
the centripetal acceleration. Draw a force diagram showing all the forces on the object.
(a) The earth, rotating around the sun
(b) A bicycle being ridden around a corner on a banked velodrome
(c) A person sitting in a car travelling around a bend
In a popular amusement park ride, people stand on a circular platform which sits inside a vertical cylinder. As the cylinder and platform spin about a vertical axis, the riders feel as if they are pushed against the inside wall of the cylinder. Once the rotation rate becomes sufficiently high, the “floor” of the ride drops, leaving those inside effectively pinned to the wall. Draw force diagrams for the following cases. Is your force diagram consistent with the requirements for circular motion? Justify your answer.
(a) The platform and the cylinder are spinning slowly. The people inside are standing on the
floor.
(b) The platform and the cylinder are spinning at high speed and the floor has been lowered.
