Question

State two applications of newton's law of gravitation

Answer 1

Applications:
           (1).  Planets and other steller objects revolve around the sun due to this force.
          (2).  Determination of value of acceleration due to gravity 'g'.
         (3).  Determination of distances of stationary orbits.
         (4). Determination of escape velocity.

Answer 2

Application of the universal law of gravitation:

1)We use this to calculate the force or pull of gravity of the planets of the earth, earth included.

2)This law also comes in handy when calculating the trajectory of astronomical bodies and to predict there motion.
