Gravitational Field Flashcards
1
Q
gravitational field
A
a region of space where a mass experiences a gravitational force
2
Q
line of force
A
direction of gravitational force acting on a small test mass
3
Q
newton’s law of gravitation
A
gravitational force of attraction between teo point masses is directly proportional to the product of the masses and inversely proportional to the square of separation between the masses
F=G(m1m2/r2)
4
Q
gravitational field strength
A
gravitational force of attraction per unit mass acting on a small test mass placed at that point in the field
5
Q
gravitational potential
A
work done per unit mass in bringing a small test mass from infinity to that point in the field
