Motion in a Vertical Circle - Georgia State University

Motion in a Vertical Circle. The motion of a mass on a string in a vertical circle includes a number of mechanical concepts. It must satisfy the constraints of centripetal force to remain in a circle, and must satisfy the demands of conservation of energy as gravitational potential energy is converted to kinetic energy when the mass moves downward. The velocity must increase as the mass moves ...

PHYSICS 111 HOMEWORK SOLUTION #9

The frictionless motion of the system guarantees energy conservation: at rest this energy is zero. Once the heavier mass m 2 is released to a lower position from rest, mass m 1 will rise and start gaining speed and higher gravitational potential energy. A maximum speed is reached when it is on a vertical posi-tion.
