Gravitation Flashcards
Recall Newton’s Law of Gravitation.
The gravitational force of attraction between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation.
State what is meant by gravitation field.
A **field of force **where force of attraction will be experienced by another mass placed in this region.
What is gravitational field strength? Derive its formula from its definition and Newton’s Law of Gravitation.
Gravitational field strength g is the gravitational force acting per unit mass.
What is gravitational potential energy?
It is work done by external agent in bringing a body from infinity to the point.
What is gravitational potential?
Gravitational potential energy ø is work done per unit mass by external agent in bringing a body from infinity to the point.
