Question

what is the difference betweeen universal gravitation and accelarartion due to gravity

Answer 1

Hey!

__________________________

Difference between 'g' and 'G'

g= acceleration due to gravity
G= Universal gravitational constant


• Acceleration due to gravity is the acceleration produced in an object in free fall due to the gravitational force of the earth.

While, Universal gravitational constant is equal to gravitational force between two objects of unit mass each and separated by a unit distance.

• Value of 'g' is constant at a given place but varies from place to place on earth. Like, if taken at the centre of the earth, g=0

The value of 'G' is constant, it isn't affected by position, that's why it is called 'UNIVERSAL CONSTANT.

• Value of 'g' is different on different surfaces of heavenly bodies.

Value of 'G' is constant.

• The value of 'g' can be zero.
The value of 'G' cannot be zero.

• Mean value of 'g' on the surface of the earth is 9.8 m/s^2.


Accepted value of G is 6.673×10^-11 N m^2 kg^2.
