3. Summary: Last class had a standard opening
Summary: Last class had a standard opening. We read from chapter 5, section 4. We watched 2 quick videos on gravity.

4. Answer the last class’s EQ which was:
Essential Question: Determine the acceleration of a falling object

5. Topic/Objective:
Name:
Gravity
Class/Period:
Date:
Dec 2
Essential Question:The Law of Universal Gravitation states force increases as what increases?

6. Warm Up

7. 1. Why does the Sun’s gravity not cause things to fly from Earth into space?

8. 2. A scale measures weight on the Earth of a man, and records a weight of 84 kg. The same scale records the same man’s weight on the moon as 14 kg. Why?

9. 3. Weight is a record of what force?

10. 4. Mass is a record of what?

11. Answers

12. 1. Why does the Sun’s gravity not cause things to fly from Earth into space?

13. 1. Why does the Sun’s gravity not cause things to fly from Earth into space? Earth is too far away to have objects that affected by the Sun’s gravity

14. 2. A scale measures weight on the Earth of a man, and records a weight of 84 kg. The same scale records the same man’s weight on the moon as 14 kg. Why?

15. 2. A scale measures weight on the Earth of a man, and records a weight of 84 kg. The same scale records the same man’s weight on the moon as 14 kg. Why? The force of gravity on the moon is 1/6th that of Earth, thus the scale reads 1/6th that of on the Earth.

16. 3. Weight is a record of what force?

17. 3. Weight is a record of what force? The downward pull of gravity.

18. 4. Mass is a record of what?

19. 4. Mass is a record of what? The amount of matter (atoms) an object possesses.
