a. Universal gravitational constant:
G is defined as the force of attraction between two bodies of mass 1 kg each kept at a distance of 1 m apart from their centers.
b. Gravitational field:
The gravitational field is the field around any body or heavenly body where the force of attraction by that body is experienced.
c. Acceleration due to gravity:
Acceleration produced on a freely falling body due to the influence of gravity is called acceleration due to gravity.
d. Freefall:
When a body is falling...
