Answer 1

Answer:

gravitation force is the force which is exerted by the earth.

Answer 2

Answer

GRAVITATIONAL FORCE

• The gravitational force is a force that attracts any two objects with mass.
• We call gravitational force attractive because it always tries to pull masses together.
• It is attractive and a centre seeking force.
• It obeys inverse square law .
• It is represented by the letter 'F'.
• F= Gm₁m₂/r² where, F = Gravitational force.

                                          G= Gravitational constant = 6.67*10⁻¹¹Nm²kg⁻²

                                          m₁= mass of first body .

                                          m₂= mass of second body.

                                           r= distance between the two bodies.

• G= Fr²/m₁*m₂
• The dimensions of G=[M⁻¹L³T⁻²]
• Gravitational force between earth and moon =1.986064*10²⁰N.
