Question

What is meant by gravitational force (or force of gravity )? Give its one example.

Answer 1

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force

It is given by,

$F=\frac{G{m}_1{m}_2}{r^2}$, direction of force will be always towards the other mass along the line joining the two bodies.

It is attractive force in nature.

because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!

bigger mass dominate this force and if two bodies of smaller mass is present then the force will be very less which may not be felt

This is called Newton's Universal Law of Gravitation.

Some examples of the force of gravity include:

• The force that holds the gases in the sun.
• The force that causes a ball you throw in the air to come down again.
• The force that causes a car to coast downhill even when you aren't stepping on the gas.
• The force that causes a glass you drop to fall to the floor.
• 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 propels a toddler down a slide.
• The force that causes the moon to revolve around the Earth.
• The force that keeps Jupiter's moons located around the planet.
