Gravity

Application of Gravitational Law We can determine acceleration due to gravity at any point using Newton’s law of gravitation. Besides we can determine mass of…

Escape Velocity If we drop a thing from up it falls downward. If we throw a stone vertically upwards, it rises to a maximum height…

Centre of mass We know, a body is composed of many small particles. If it is considered that all the masses of these small particles…

Centre of Gravity We know, the amount of force by which an object is attracted towards the centre of the earth is called its weight.…

Variation due to the rotation of the earth about its axis: Since the earth is continuously rotating about its own axis, except the bodies present…

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…
