Gravitation Worksheet
1. A box has a mass of 40.0-kg. Find it’s weight on:
A). Earth
B). on a planet that is 3 times as massive
C). on a planet that is ¼ as massive
D). on a planet with 5 times the radius.
E). on a planet with 1/3 the radius
F). On a planet with 4 times the mass and 2 times the radius
G). On a planet with 1/3 the mass and 4 times the radius
2. Discuss what type of planet you will weigh the LEAST on. Discuss the mass, radius, and
density of the planet.
3. Discuss where on Earth you will weigh the most. Discuss the location as well as the terrain.
4. A satellite of mass 5.5 x 10 3 is placed in orbit above the Earth. If it is located 4.4 x 10 5
meters ABOVE the Earth, find the satellites velocity. (Set gravitational force = to centripetal
force).
5. Find the acceleration due to gravity on planet Zot if the mass of the planet is 2.24 x 10 26 kg
and its radius is 4.57 x 10 5 meters.
6. Find the gravitational force between Sue (mass = 55.0-kg) and Fred (mass = 75.0-kg) if the
distance between them is 0.75 meters.
