Mention any two points of importance of universal law of gravitation?

Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

As per the universal law of gravitation, every object in the universe attracts every other object by the force of attraction which is directly proportional to the product of masses of the objects and is inversely proportional to the square of the distance between them. This is mathematically given as:

F = G(mM/d2)

Where,

• F is the force of the gravitational pull
• G is the constant known as the gravitational constant
• M is the mass of object 1
• m is the mass of the object 2
• d is the distance between object 1 and object 2

Importance of universal law of gravitation

• We can calculate the force or pull of gravity of the planets in-universe.
• We can also determine the trajectory of astronomical bodies and to predict their motion
• It pulls all the object towards the earth.
• The motion of planets around the Sun.
