Question

define:a) gravitational force

Answer 1

Gravitational Force


Gravitation force is well known word in physics. Gravity force exists in all masses objects, i.e. all the object which have masses. The gravitational force is exhibited from the lighter mass to heavier mass.

The expression for the gravitational force is,

Here, F is the gravitational force, G is the gravitational constant,  is the mass of one object,  is the mass of another object, and R is the distance between the two objects.

Thus, the gravitational force is directly proportional to the product of the mass of the massive objects and inversely proportional to the square of the distance between the objects. This is known as Newton's law of gravitation.

The gravity force exists in atoms, light particles, planets, and starts as their energies and masses are same.

. Nine planets namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto move around the Sun. These nine planets and the Sun are known as Solar System. The gravitational attraction holds all the nine planets and the Sun in the solar system.

To get the weight of the object that has mass, the gravitational acceleration should be multiplied with the mass.

There are four fundamental forces in the Universe, i.e. gravity force, weak interaction force, strong interaction force and electromagnetic force. Among these forces, gravity force is the weakest force.

Answer 2

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.
