Gravity 2

Force, weight, and gravity  questions.

1. What is the mutual effect of mass objects ?

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

3. What is the weight of an object with the mass of 5 kg on the Earth surface?

4. What is gravitationanal field strength? Give definition.  (Intensity of gravitational field) 

5. 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?

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

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

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

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