Question

please tell all the answer​

Answer 1

Answer:

Explanation:

1) Displacement is 0 when body the comes to initial point after motion.

2)The gravitational force between earth and any object is known as gravity.

Difference Between Gravitation and Gravity

It is a universal force It is not a universal force

It is a weak force It is a strong force

The force is F=(GM_{1}M_{2})/R^{2} (G= gravitational constant) The force is F=mg (g=acceleration due to gravity)

3)energy

4)time = work/power

 =520/20=26 sec

5)momentum because time taken more force is less.

6)
