7 G Field

Question 1

Newton’s Law of Gravitation

Answer 1

Newton’s Law of Gravitation states that the gravitational force between two point masses is proportional to the product of masses and inversely proportional to the square of separation.

Question 2

Gravitational potential

Answer 2

Gravitational potential at a point in a gravitational field is the work done per unit mass by an external agent in bringing a small test mass from infinity to that point.

Question 3

Gravitational potential energy

Answer 3

Gravitational potential energy of a small test mass at a point in a gravitational field is the work done by an external agent in bringing the mass from infinity to that point without any change in its kinetic energy.
