what is Difference between gravitation and gravity
Answers
Answer:
The gravitational force between earth and any object is known as gravity.
Difference Between Gravitation and Gravity
Gravitation - The force is F=(GM_{1}M_{2})/R^{2} (G= gravitational constant)
GRAVITY - The force is F=mg (g=acceleration due to gravity)
Answer:
The difference between Gravitation and Gravity is mentioned below:
- g is the symbol for acceleration due to the gravity and G is the symbol of universal law of gravitation that is gravitational constant.
Gravitation:
➟ The gravitational force of earth is known as gravity i.e., gravity is the force by which earth pulls a body toward it's centre.
➟ Gravitation- Every body attract other body by a force called force of gravitation.
➣ Newton's law of gravitation- The force of gravitational attraction between two points bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Considering two points are placed at a distance The force of gravitational attraction between them,
Here is constant called universal gravitational constant. The value of G is

Now let's derive...
↪️ Let two objects A and B of masses M and m lie at a distance, d from each other.
Now let the force of attraction between then be F.
↪️ Now according to the universal law of gravitation, the force between two objects is directly proportional to their masses. Therefore,
→ F ∝ M × m
→ F ∝ Mm – – – Equation 1
↪️ And we also know that the force between two objects is inversely proportional to the square of the distance between them. Therefore,
→ F ∝ 1/(d)² – – – Equation 2
↪️ From – – – Equation 1 and 2
→ F ∝ Mm/(d)²
Let's remove proportional sign, by adding constant as G here
→ F = GMm/(d)²
Henceforth,
→ G = Fd²/Mm Henceforth, derived!
Gravity:
➟ The acceleration produced in a body due to force of gravity is known as acceleration due to gravity. Acceleration due to gravity is denoted by “g”. And g's value is 9.8 m/s².
➣ Acceleration due to gravity is independent of shape, mass and size of the mass of the body.
➟ The gravitational force of earth is known as gravity i.e., gravity is the force by which earth pulls a body toward it's centre.
