What is the formula of gravitational force Class 11?
Law of Gravitation Directly proportional to the product of their masses, i.e. F ∝ (M1M2) Inversely proportional to the square of the distance between their centre, i.e. (F ∝ 1/r^2)

Is gravitation important for JEE mains?
Gravitation is an easy to understand and a highly scoring topic. Not the most important. But yes you can expect 1-2 questions from this topic, which could be solved easily.
What is the formula to solve for gravitational force?
To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object’s mass by 9.8 and you’ll get its force of gravity!
What is V in gravitation?
The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.
What is the formula for calculating gravity?
What is gravity in circular motion?
Centripetal forces cause centripetal accelerations. In the special case of the Earth’s circular motion around the Sun – or any satellite’s circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them.
What is circular gravity?
Circular Orbit Gravity supplies the necessary centripetal force to hold a satellite in orbit about the earth. The circular orbit is a special case since orbits are generally ellipses, or hyperbolas in the case of objects which are merely deflected by the planet’s gravity but not captured.
What is the formula for gravitational force between two objects?
Find out how to calculate gravitational forces We can do this quite simply by using Newton’s equation: forcegravity = G × M × mseparation2 . Suppose: your mass, m, is 60 kilogram; the mass of your colleague, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 -11 newton square metre kilogram-2.
What is g GM r2?
g = GM/r2, Where M is the mass of the Earth, r the radius of the Earth (or distance between the center of the Earth and you, standing on its surface), and G is the gravitational constant.
What is m * g?
m is the mass of the object. g is the acceleration due to gravity; this number is a constant for all masses of matter. mg is the product of m times g.
Why is g GM r2?
The above acceleration is due to the gravitational pull of earth so we call it acceleration due to gravity, it does not depend upon the test mass. Its value near the surface of the earth is 9.8 ms-2. Therefore, the acceleration due to gravity (g) is given by = GM/r2.
What is g in FG Gm1m2 r2?
Newton’s Law of Gravita- tion states that two objects with masses m1 and m2, with a distance r between their cen- ters, attract each other with a force F given by: F = Gm1m2/r2 where G is the Universal Grav- itational Constant (equal to: 6.672 x 10-11Nm2/kg2).
What is the formula for the force of gravity?
This equation presents the force of gravity between an object with mass m 1 and another object of mass m 2 and a distance between them of r. 2) G = 6.67 x 10 -11 N m 2 / Kg 2 ; G is the universal constant of gravity;
What is the formula for gravitational field intensity?
∴ \herefore ∴ I = G M r 2 \\frac {GM} { { {r}^ {2}}} r2GM , which is the required expression for gravitational field intensity.

What is the value of universal gravitational constant?
, where G is proportionality constant called universal Gravitational constant. The value of G is 6.67×10 –11 Nm 2 kg –2 For m 1 = m 2 = 1kg and r = 1m, then we have Thus, universal gravitational constant (G) can be defined as the gravitational force between two objects of unit mass whose centers are unit distance apart.
