Introduction - we are going to identify one of the forces which produces acceleration in all objects on the surface of the Earth irrespective of their mas..

Astronomy has been a fascinating subject from ancient times. The geocentric system (around the 2nd century A.D.) considered the Earth to be at the centre with the sun and other planets revolving around i..

Earth is the only planet in our solar system, which is surrounded by oxygen, the life giving gas. It is the only planet to have large quantities of water. Earth's atmosphere contains oxygen, nitrogen, carbon dioxide and water vapour. Earth Earth is a medium s..

The earth's magnetic field has an axis which is inclined 20 o west of the axis of rotation of earth. The point where this huge earth's magnet cuts the earth's surface are the magnetic poles. A freely suspended magnet has its north pole pointing towa..

Gravitational Potential Energy Near the Surface of Earth - As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg..

As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg) can be assumed to be constant. Consider a body of mass 'm', lying on the surf..

Introduction - We have learnt that a force changes or tends to change the state of rest, speed or direction of motion of an object, i.e., the force produces an acceleration. In this chapter, we are going to identify one of the forces which produces acceleration in all objects on the surface of the ..

Force of Gravitation - Drop a stone from a height. What do you observe? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. The stone is not moving with uniform speed. Its speed keeps changing at every insta..
