Introduction to

Gravitational force

I am issac newton

I was born in January 4,1643 in UK. I was an established physicist and mathematician, and famous for my law of

gravitation, was instrumental in the scientific revolution of the 17th century.In 1687, I published my most acclaimed

work, Philosophiae Naturalis Principia Mathematica.I died in London on March 31, 1727.

What is Gravitati

onal force?

Force that exists amoung all material objects in the universe.

For any two objects or particles having non zero mass force of gravity tends to attract them towards each other.

How Does Gravitational force Work

Gravitational forceGravitational force amoung two spherical having uniform density is directly propportioma; to the product of their masses and inversely proportional to the square of the distance between them.

• The gravity of Earth, which is denoted by g.• It refers to the acceleration that the Earth imparts to objects on or

near its surface due to gravity.• In SI units it is measured in m/s2 or m·s−2 or equivalently N/kg or

N·kg−1. It has an approximate value of 9.8 m/s2

Gravitational forces in Solar system

All planets in solar system are revolving around sun due to gravitational force.

Moon is also orbiting Earth on same phenomena

GRAVITationational forces applications

The force that causes a ball

you throw in the air to come down again.

The force that keeps the Earth

and all of the planets in line in

the proper position in their orbits around

the sun.

The force that holds the gases in the sun.

ConclusionGravitational Force is necessary for our

existance.Without Gravity our universe will collapse.
