Question

how is Newton's 2nd law of motion related to universal law of gravitation​

Answer 1

Answer:

Explanation:

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. ... The weight of an object is defined as the force of gravity acting on an object of mass .

Answer 2

Answer:

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. ... The weight of an object is defined as the force of gravity acting on an object of mass .

Explanation:

By Newton’s second law of motion

F=mg ...(i)

By universal law of gravitation

F=

r

2

GMm

From (i) and (ii) we have

mg=

r

2

GMm

⇒g=

r
