Gravitational Field

Question 1

gravitational field

Answer 1

a region of space where a mass experiences a gravitational force

Question 2

line of force

Answer 2

direction of gravitational force acting on a small test mass

Question 3

newton’s law of gravitation

Answer 3

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)

Question 4

gravitational field strength

Answer 4

gravitational force of attraction per unit mass acting on a small test mass placed at that point in the field

Question 5

gravitational potential

Answer 5

work done per unit mass in bringing a small test mass from infinity to that point in the field
