Question

What do you mean by gravitational force. Give an short example to illustrate it

Answer 1

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive 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.
For example, the earth revolving around the sun is an example for gravitational force, ie, the sun pulls the earth around it.
