Question

Write any four difference between acceleration due to gravity and universal gravitational constant.

Answer 1

Answer:

✅it is gravitational constant.

✅the gravitational force between two bodies of unit masses separated by a unit distance is known as universal gravitational constant.

✅the value of 'G' is same at every place of the earth or universe.

✅the value of 'G' does not change with height and depth from the surface of the earth.

✅the value of 'G' is not zero at the centre of the earth or anywhere else.

✅its value is 6.6734 × 10^-11 N m²/kg² throughout the universe.

✅its SI unit is N m²/kg²

✔️acceleration due to gravity 'g' :-

---------------------------------------------

✅it is an acceleration due to gravity.

✅the acceleration produced in a body falling freely under the action of gravitational pull of the earth is known as acceleration due to gravity.

✅the value of 'g' is different at different places of the earth.

✅the value of 'g' decreases as we go higher from the surface of the earth or as we go deep into the earth.

✅the value of 'g' at the centre of the earth is zero.

✅its value is 9.8m/s² on the surface of the earth.

✅its SI unit is m/s².
