Gravitation

1. Concept Overview The mass and density of Earth are fundamental parameters in understanding gravitational attraction, planetary motion, and satellite

The value of acceleration due to gravity changes with height (i.e. altitude), depth or shape of the earth and rotation

Effect of Depth on Acceleration Due to Gravity If we consider a B at a depth of d below the earth surface

The radius of the Earth is more at the equator than at the poles. Due to this, the value of

1. Statement of the Concept The time period of a satellite is the time taken by the satellite to complete

1. Concept Overview When a satellite revolves around the Earth in a circular orbit, its orbital radius ([r]) is the

1. Concept Overview The binding energy of a satellite is the minimum energy required to remove the satellite completely from
