Newtons Law of Universal Gravitation Physics PHYS101

for more free video tutorials covering Physics. This video illustrates Newtons law of universal gravitation following necessary equations and diagrams.
The law states that every particle in the universe attracts each other and the force acting between any two particles is known as gravitational force.
Next the formula has shown and it has demonstrated in details that how gravitational force acting between any two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. Moving on the video clears the contradiction between universal gravitational constant and the gravitational acceleration following the derivation of gravitational acceleration from Newtons law of universal gravitation.
Both the universal gravitational constant and acceleration due to gravity have standard constant value.
Last part of the video briefly describes an example asking to find out gravitational force between earth a person for some specified condition.
It is quite necessary to have clear concept on gravity to understand this video content.
