Universal Gravitation Physics 1 Review 1. State Newton’s Law of Universal Gravitation _____________________________________________ ______________________________________________________________________________ 2. What does gravitational force depend on? ______________________________________________ 3. Which way does it act? ______________________________________________________________ 4. If a gravitational force exists between two bodies of different masses, which one feels the stronger force? ____________________________________________ 5. If a gravitational force exists between two bodies of different masses, which one experiences more acceleration? _______________________________________ Why? ________________________ 6. How does distance affect gravitational force? ____________________________________________ 7. If the distance between two objects doubles, what happens to the gravitational force between them? ______________________________________________________________________________ 8. Is the gravitational force constant or varying? ____________________________________________ 9. What is the Universal Constant of Gravitation? ___________________________________________ 10. Who calculated the Universal Constant of Gravitation? _____________________________________ 11. Describe his experiment to determine this constant. ________________________________________ _______________________________________________________________________________ 12. A 2000 N truck is parked 20 meters from a 2500 N truck. What is the gravitational force between them? A 3m B 3m C 13. Three objects A, B, and C are arranged as shown. If objects A and B have masses of 70 kg each and object C has a mass of 90 kg, what is the total gravitational force on object B? 14. For problem 13, what is the total gravitational force on object A? 15. For problem 13, what is the acceleration of object C? 16. Three objects A, B, and C are arranged as shown. If objects A and B have masses of 70 kg each and object C has a mass of 90 kg, what is A B 3m 90° the total gravitational force on object B? 3m C 17. For problem 16, what is the total gravitational force on object A? 18. For problem 16, what is the acceleration of object C?
