NEWTON’S THIRD LAW OF MOTION
4. Sir Isaac Newton was born on 4th January 1643 in a
village of England called Woolsthorpe-by-Colsterworth.
He was an English physist and mathematician, and one
of the important thinkers in the Scientific Revolution.
5. He discovered the phenomenon of white light integrated
with colours which further laid the foundation of
modern physical optics . His famous three laws of
Motion in Mechanics and the formulation of the laws of
gravitation completely changed the track of physics
across the globe. A scientist like him is considered as an
excellent gift by nature to the world of physics.
6. Sir Isaac Newton was the first individual to develop
calculus. Modern physics and physical chemistry are
almost impossible without calculus, as it is the
mathematics of change.
The idea of differentiating calculus into differential
calculus, integral calculus and differential equations
came from Newton’s fertile mind. Today, most of the
mathematician give equal credit to Newton and
Leibniz for calculus’s discovery.
7. The famous apple that he saw falling from a tree led him to
discover the force of gravitation and its laws. Ultimately, he
realized that the pressure causing the apple’s fall is
responsible for the moon to orbit the earth, as well as
comets and other planets to revolve around the sun. The
force can be felt throughout the universe. Hence, Newton
called it the Universal Law Of Gravitation.
8. Sir Isaac Newton put forward the universal law of gravitation
in 1687 and used it to explain the observed motions of the
planets and moons. In this article, let us familiarize ourselves
with Newton’s Law of Universal Gravitation.
Newton’s Law of Universal Gravitation states that every
particle attracts every other particle in the universe with force
directly proportional to the product of the masses and
inversely proportional to the square of the distance between
them.
9. Newton’s conclusion about the magnitude of gravitational
force is summarized symbolically as
F=Gxm1xm2/r2
where, F is the gravitational force between bodies, m1 and
m2 are the masses of the bodies, r is the distance between
the centres of two bodies, G is the universal gravitational
constant.
The constant proportionality (G) in the above equation is
known as the universal gravitation constant. Henry
Cavendish experimentally determined the precise value of G.
The value of G is found to be G = 6.673 x 10-11 N m2/kg2.
10. A body remains at rest, or in motion at a constant
speed in a straight line, unless acted upon by a force.
11. When a body is acted upon by a force, the time of
rate of change of its momentum equals the force.
12. If two bodies exert forces on each other, these
forces have the same magnitude but opposite
direction. In other words for every action there is
an equal and opposite reaction.
