Question

7. Why 'G' is called universal gravitational constant?

Answer 1

Answer: Capital G will be constant become the value of the G will be constant anywhere in the Universe.

Answer 2

G is called Universal Gravitation Constant because its value i.e. 6.67 x 10-11 Nm2kg-2 is constant thought the universe

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”.
