I was going through a site which tells:
F=G.m1.m2r^2
Also
F=-G.m.m/r^2.
Can it be written?
Thanks.
F=G.m1.m2r^2
Also
F=-G.m.m/r^2.

Thanks.
The first version makes no sense.shounakbhatta said:I was going through a site which tells:

Sometimes when writing the force as a vector expression a minus sign is used to indicate that it's an attractive force:shounakbhatta said:Sorry,

Can it be written:
F=-G.m.m/r^2.

The Law of Gravitation, also known as Newton's Law of Universal Gravitation, is a physical law that describes the force of gravitational attraction between two objects with mass. It states that every object in the universe exerts a gravitational pull on other objects, and this force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The Law of Gravitation was discovered by Sir Isaac Newton in the late 17th century. He developed this law based on his observations of the motion of celestial bodies, such as the moon and planets, and his theory of gravity.
The Law of Gravitation explains the force that causes objects to move towards each other. It is responsible for the motion of planets around the sun, as well as the motion of objects on Earth. It also explains why objects fall towards the ground when dropped.
The equation for the Law of Gravitation is F = G * (m1 * m2)/r^2, where F is the force of gravitational attraction, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. This equation can be used to calculate the force of gravity between any two objects in the universe.
The Law of Gravitation is responsible for the orbital motion of celestial bodies, such as planets, around larger objects like stars. It explains why these bodies move in elliptical paths and how the strength of gravity affects their speed and trajectory. It also plays a crucial role in keeping our solar system stable and in maintaining the balance of the universe.
