Science > Physics > Gravitation > Escape Velocity of a Body If the velocity of upward projection is increased, a stage will be reached when the velocity given to the body is such that, the kinetic energy of the body is sufficient to overcome the gravitational influence of the earth. This velocity is known as […]
Science > Physics > Gravitation > Binding Energy of Satellite In this article, we shall study the concept of the binding energy of satellite and its significance. The binding energy of a satellite can be defined as the minimum amount of energy required to be supplied to it in order to free the satellite from […]
Science > Physics > Gravitation > Numerical Problems on Critical Velocity and Period of Satellite Example – 18: A satellite revolves around a planet of the mean density of 104 kg/m3. If the radius of its orbit is only slightly greater than the radius of the planet, find the time of revolution of the satellite. G […]
Science > Physics > Gravitation > Numerical Problems on Critical Velocity and Period of Satellite In this article, we shall study to solve problems to calculate time period and orbital speed of satellite. Example – 01: Calculate the speed and period of revolution of a satellite orbiting at a height of 700 km above the […]
Science > Physics > Gravitation > Critical Velocity and Time Period of Satellite In this article, we shall derive expressions for the critical velocity and time period of a satellite in different forms. Critical Velocity: The constant horizontal velocity given to the satellite so as to put it into a stable circular orbit around the […]
