why is the law of gravitation said to be Universal? give the equation for universal gravitation explain clearly the significance of this law
Answers
Every particle in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This force acts along the line joining the two particles. This is known as universal law of gravitation.
Expression.
Let us consider two bodies of masses m1 and m2 are separated by a distance r.
According to Newton's Gravitaional Law
F is directly proportion to m1m2
So F is inversely proportional to 1/r^2
On combination
F=Gm1m2/r^2
It's significance is..
Gravity creates stars and galaxies, orders the motion of planets, moons and sputmiks, and makes your loose change stay in your pocket...
Hope the answer is Good.
