2
Q
What is Equipotential surface?
A
When an object move in a gravitational field in such a way that its energy doesn’t change
3
Q
What is the newton law?
A
The gravitational force between 2 particles is proportional to the product of 2 masses of the particles and inversely proportional to the square of the distance between particles F = GMm/r^2
