Differbetween
Even though both the terms sound alike but there is a difference between gravitation and gravity, gravitation is the force occurring between two bodies whereas gravity is the force occurring between the earth and a body.

What do you mean by gravity and gravitation?
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
Is gravity G or G?
G or g. g is the acceleration of gravity 9.8 (m/s2) or the strength of the gravitational field (N/kg) (which it turns out is equivalent). When acceleration acts on a physical body, the body experiences the acceleration as a force.
What is gravitation class 9th?
Every object in the universe attracts other object by a force of attraction, called gravitation, which is directly proportional to the product of masses of the objects and inversely proportional to the square of distance between them. This is called Law of Gravitation or Universal Law of Gravitation.
What is the force of gravity formula?
The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
Why gravity is always attractive?
In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces.
Why is gravity 9.81 ms 2?
Gravity (or the acceleration due to gravity) is 9.81 meters per second squared, on the surface of Earth, because of the size of Earth and the distance we are on its surface from its center. ... Throughout space, gravity actually is constant.
What is Big G equal to?
In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.
What is G called?
The gravitational constant G is a key quantity in Newton's law of universal gravitation.
...
Gravitational constant.
| Values of G | Units |
|---|---|
| 4.30091(25)×10−3 | pc⋅M⊙–1⋅(km/s)2 |
What do you mean by free fall class 9?
The gravity of the earth attracts every object towards its centre. When an object is dropped from a certain height, it begins to fall towards Earth's surface under the influence of gravitational force. Such a motion of an object is called free fall.
What is the value of G on moon Class 9?
The acceleration due to gravity on moon or the value of g on moon is 1.625 m/s2.
What is Work class 9?
Work done on an object is defined as the product of the magnitude of the force acting on the body and the displacement in the direction of the force. W = F.s. If a force acting on a body causes no displacement, the work done is 0. For example, pushing a wall.
