gravitational field Flashcards
1
Q
gravitational field
A
a region in which a gravitational force acts on a mass placed at any point within the region
2
Q
Newton’s Law of Gravitation
A
the mutual 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 distance apart.
3
Q
gravitational field strength at a point
A
gravitational force exerted per unit mass placed at that point
4
Q
gravitational potential
A
work done per unit mass by external force in bringing a small test mass from infinity to that point
