G Field

Question 1

Gravitational Force

Answer 1

Newton’s law of gravitation states that the force of attraction between two point masses is proportional to the product of their masses and inversely proportional to the square of their separation

Question 1

Gravitation Field

Answer 1

A gravitational field is a region of space where a mass experiences a gravitational force.

Question 2

Gravitational Potential

Answer 2

The gravitational potential at a point is the work done per unit mass by an external agent in bringing a small test point mass from infinity to that point without a change in kinetic energy.

Question 3

Gravitational Potential Energy

Answer 3

The gravitational potential energy is defined as the work done by external force in bringing a small test mass from infinity to that point without a change in kinetic energy.

Question 4

Gravitational Field Strength

Answer 4

Gravitational field strength at a point is defined as the gravitational force per unit mass acting on a small test mass placed at that point.
