Newtons Law Of Gravitation

Question 1

State Newton’s universal law of gravitational

Answer 1

Every particle in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centers.
F = G x m1m2/r^2

Question 2

Define gravitational field

Answer 2

A region in space where a mass will experience a force.
It is the force acting per unit mass
g = F/m where F is the force experiences by mass (m) in a gravitational field (g)

Question 3

Gravitational field VS acceleration due to gravity

Answer 3

These are equivalent
Acceleration due to gravity can be calculated using: g = G M/r^2
