Gravity and Gizmo

Here are the answers to the gravity sheet.
1. F= 9.34 x 10^-6 N. This is basicallly the force between you and your car when you are at the door.
2. 5.28 x 10^-10 N
3. 4.42 N
4. 7.33 x 10^22 kg
5. a. 9.8 m/s/s ... it shows you how we derive "g" on Earth.
b. Acceleration due to the force of gravity of Earth
c. Earth's mass and radius
...so you have just learned how "g" was determined...
6. 1.99 x 10^20 N
7. 4848 N
8. 3.52 x 10^22 N


Now for the extra credit, have your yellow sheet handy and go here.
Must be turned in Monday. Have a great weekend!
