What is gravitational force ? Derive it.
Answers
Answer:
Explanation:
Every body in the universe attracts every other body with a force that is equal to product of their masses and inversely proportional to square of the distance between them.
Consider two bodies of mass m1 and m2 separated by distance r
F proportional to m1m2/r^2
F=Gm1m2/r^2
G is a constant called universal gravitational constant
Explanation:
✧ What is the Gravitational Force?
✒The universe has a lot of forces, a lot of pushes and pulls. We're always pushing or pulling something, even if only the ground. But it turns out that in physics, there are really only four fundamental forces from which everything else is derived: the strong force, the weak force, the electromagnetic force, and the gravitational force.
☞︎︎︎ Additional information
☞︎︎︎In the equation:
F is the force of gravity (measured in Newtons, N)
G is the gravitational constant of the universe and is always the same number
M is the mass of one object (measured in kilograms, kg)
m is the mass of the other object (measured in kilograms, kg)
r is the distance those objects are apart (measured in meters, m)
So if you know how massive two objects are and how far they are apart, you can figure out the force between them.
