Material Research of Escape Velocity

We know, escape velocity of the earth is 11.2 kms-1. That means, in order to escape from the earth or in order to escape the......

Why Satellite Revolving very near to the Earth’s Surface?

Satellite revolving very near to the earth’s surface: If a satellite remains very near to the earth’s surface, i.e., if h is very small compared......

Summary of Galileo’s Laws and Keplers’ Laws

Summary of Galileo’s Laws and Keplers’ Laws Galileo’s laws: First law: In vacuum all the freely falling bodies starting from rest traverse equal distance at......

Geo-stationary Satellite

Geo-stationary satellite: If an artificial satellite is placed in an orbit of the equatorial plane in such a way, that it is concentric and coplanar......

Velocity of the Artificial Satellite

Velocity of the artificial satellite Suppose the height of a satellite is h from the surface of the earth and if R is the radius......

How to Launch an Artificial Satellite in the Space?

Launching of an artificial satellite in the space: In order to place an artificial satellite in the orbit, necessary very high velocity is provided by......

Artificial Satellite Explanation

Artificial Satellite Artificial satellites are human-built objects orbiting the Earth and other planets in the Solar System. The satellite that is created by man based......

What is Natural Satellite and Artificial Satellite?

Natural satellite: The materials or stars which revolve round a planet are called satellites. The satellites which are created naturally are called natural satellites. For......

Orbital Velocity

Orbital velocity Objects that travel in uniform circular motion around the Earth are said to be “in orbit”. The velocity of this orbit depends on......

Application of Gravitational Law

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

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

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......

Explain Centre of Gravity

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

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)

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......
