Force, weight, and gravity 1

Force, weight, and gravity  questions.

1.  What is gravitational force?

2 How does gravitational force manifest itself?   What is the mutual effect of mass objects ?

3. How does the gravitational force depends on the distance of the mass objects?

4. What is weight?

5. How do you see the difference between mass and wight?

6. What is the weight of an object with the mass of 5 kg?

7. How can you characterize gravitational field?   What is it?

8. What is gravitationanal field strength?  (Intensity of gravitational field)

 9. We have an object with mass 100 kg  on the Earth surface.

 a. What is its mass in the open Universe with no significant mass objects nearby?

b. What is its weight  in the open Universe with no significant mass objects nearby?

10. We have an object with mass 100 kg  on the Earth surface.The gravitational field strength (acceleration)on on the Moon is 1.66 N/kg.

a. What is its mass on the Moon?

b. What is its weight on the Moon?

11. What is the formula for calculating weight if we know the mass and gravitational field force?

W= ........................?

12. If we know the weight and gravitational field force (acceleration) how do we calculate mass?

g=...........................?

13. What are two meanings of  g?
