Chapter 5: Circular Motion and Gravity

A ball is whirled in a horizontal circle of radius r and speed v. The radius is increased to 2r keeping the speed of the ball constant. The period of the ball changes by a factor of

- one half.
- one.
- two.
- three.

Suppose a planet exists that has half the mass of earth and half its radius. On the surface of that planet, the acceleration due to gravity is

- twice that on Earth.
- the same as that on Earth.
- half that on Earth.
- one-fourth that on Earth.
- none of these.

- R = Gv/M
- R = Gv/mM
- R = GmM/v
- R = GM/mv
- R = GM/v2

- R = Gv/M
- R = Gv/mM
- R = GmM/v
- R = GM/mv
- R = GM/v2

- A line joining any planet to the sun sweeps out equal areas in equal times.
- Only an odd number of planets can orbit the sun.
- The period of any planet about the sun is proportional to the planet's distance from the sun.
- All planets move in elliptical orbits with the earth at one focus.
- F = GMm/R2
