Physics one-liners for various competitive examinations

Welcome to the Physics Section page.

We know the importance of general awareness, GK (General Knowledge) in various competitive exams for aspirants.

We are publishing general awareness notes and study material on various subjects daily.

These Physics notes are extremely useful for all exams including Bank Exams.

Gravitational Force

 

Gravitational Force- It is the force of mutual attraction between any two objects by virtue of their masses.


* It is a universal force.


* All objects on the earth experience the force of gravity due to the earth.


* It is gravity that governs the motion of the moon and artificial satellites around the earth, the motion of the earth and planets around the sun.


* Gravitational Force plays a key role in the large-scale phenomena of the universe, such as formation and evolution of stars, galaxies.


* The gravitational pull of the moon pulls the seas towards it, causing the ocean tides.


* The gravitational force was discovered by Sir Isaac Newton in 1687.

 


* Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.


* The sun’s gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun’s light and warmth.


* Gravity is slightly stronger over places with more mass underground than over places with less mass.


* The value of gravitational force is 9.8 m/s2 on Earth. The acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.


* Astronauts float around in space because there is no gravity in space.


* When we throw a stone upwards from earth it falls down to the earth due to the gravitational force of earth.


* The moon is orbiting around earth due to the gravitational force of the earth. Planets are orbiting around sun due to the gravitational force of the sun.


* According to Newton’s law of gravitation, The gravitational force is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.


* Gravitational force is the weakest force among the four fundamental forces of nature.
