Magnitude of Acceleration of Gravity (g) Acceleration of Gravity (g), its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity…

Variation due to shape of the earth: We know, the shape of the earth is not exactly spherical. Its north-south is slightly squeezed and east-west…

Variation of Acceleration due to Gravity We have learnt from the law of gravitation that the value of acceleration due to gravity (g) does not…

Gravitational potential due to a point mass We know, the amount of work done in bringing a unit mass from infinity to a point in…

Relation between intensity and potential difference In order to establish the relation between gravitational intensity and gravitational potential let A and B be two very…

Gravitational Intensity due to a point mass We distinguish that there are four fundamental forces in nature. The force between two bodies by virtue of…

Gravitational Potential The gravitational potential at a point due to the earth is defined as the amount of work done in moving a unit mass…

Gravitational field Intensity or Strength Definition: The gravitational field intensity or strength of an object at any point in the gravitational field is defined as…

Gravitational field Gravitational force of attraction between two bodies acts without any physical contact between these bodies. From the idea of gravitational field nature of…

Nature of gravitational force: If a body is released from above and allowed to fall without resistance it falls downward i.e., it falls on the…
