What is the acceleration due to gravity of the moon?

= 1.67 m/s².

What is the value of gravitational constant?

= $6.674\times 10^{-11}{\text{m}}^3\mathrm{/}\text{kg}\cdot {\text{s}}^2$

If the distance between two bodies is doubled, the force of attraction F between them will

=2f

If a piece of stone is dropped from a height, its speed after it has fallen 100 m will be:

=44.2m/s

The acceleration due to gravity is zero at:

=center of the earth

A feather and coin released at the same time from the same height do not reach the ground at the same time because of the:

= resistance of the air

How much would a person whose mass is 60 kg weight on the moon?

=98N

What is the relation between of a body and acceleration due to gravity?

=; w=g

Two bodies with the mass of 200 kg each are kept 2 m apart from their center on the surface of the earth. Calculate the force of attraction produced between them.

=66.7×10−7N

The earth has the mass of (6\times10^{24}) kg and its radius 6380 km. What will be the gravity of the earth to a body of mass 1 kg on the surface of the earth?

=9.8N

What is the acceleration due to gravity on the surface of the earth when its mass is (6\times10^{26}kg) and radius is 6400 km. Given, (G=6. 67\times10^{-10}Nm^{2}/kg^{2})

= 9.8m/s2

Who formulated the universal law of gravitation?

= sir issac Newton 

If the mass of a body is 9.8 kg on the earth, what would be its mass on the moon?

=9.8 kg

The relation between g and G is

=r2G⋅M​

As we go from the equator to the poles, the value of 'g'

=increases

All bodies whether large or small fall with the

=same acceleration

Weightlessness experienced while orbiting the earth in a spaceship is the result of

= zero gravity

When an object falls freely to the earth, the force of the gravity is

=d. in the same direction as the motion.

The weight of a body at the center of the earth is

=zero

The force of gravitation between two bodies does not depend on

=the mass of the third body.
