Force is inversely proportional to the square of the distance between the 2 bodies. = 7.92km / h, if v is the speed of a satellite in its orbit and vo is the required orbital velocity to move in the orbit, then. CBSE Class 11 Physics Notes : Gravitation. A polar orbit is that orbit. For Study plan details. The angle of rotation can be measured experimentally. (i) during freely falling under gravity Hindi Physics. The angular velocity of the satellite is same in magnitude and direction as that of angular. Note Newton’s law of gravitation holde goods for object lying at uery large distances and also at very short distances. However, for (i) If v < vo, then satellite will move on a parabolic path and satellite falls back to earth. = – GMm / 2r. Natural satellites are those heavenly objects which are not man made and revolve around the earth. (ii) It is conservative in nature. (iii) the strong nuclear force (also called the hadronic force). focus. (iii) Effect of Altitude The value of g at height h from earth’s surface, (iv) Effect of Depth The value of gat depth h A from earth’s surface. Gravitational Constant. Cavendish performed an experiment to calculate the value of G. To calculate the value of G he took a wooden plank and attached two 2 balls on either side of the plank and hung this with a thin thread from the top. Where G = universal Gravitational constant. You cannot hear the sound of the explosion on earth.

IndrajeetSingh Sangtani. Brain Games for Sharper Minds. NCERT Solutions for Class for Class 11 Physics Chapter 8 gives a detailed explanation of the universal law of gravitation and three vital laws proposed by Kepler. Gravitation is one of the four classes of interactions found in nature. NCERT Book for Class 11 Physics Chapter 8 Gravitation is available for reading or download on this page. where M = mass of the earth = 6.0 * 1024 kg and R = radius of the earth = 6.38 * 106 m. Acceleration due to gravity at a height h above the surface of the earth is given by, Factors Affecting Acceleration Due to Gravity. Gravitational force is a attractive force between two masses m1 and m2 separated by a distance gravitation forces between two bodies are action-reaction pairs. (iv) The law of gravitational is applicable for all bodies, irrespective of their size, shape and We hope the NCERT Solutions for Class 11 Physics Chapter 8 Gravitation help you. Kepler’s Law of Gravitation To resolve shortcomings of the models propounded by Ptolemy and Copernicus, Kepler propounded three laws on planetary motion. Class 1 - 3; Class 4 - 5; Class 6 - 10; Class 11 - 12; CBSE. or own an. There satellites revolve around the earth in polar orbits.

Dec 15, 2020 - Gravitation, Chapter Notes, Class 11, Physics (IIT-JEE & AIPMT) Class 11 Notes | EduRev is made by best teachers of Class 11. = GMm / 2r + (- GMm / r) A satellite which appears to be at a fixed position at a definite height to an observer on earth is INSAT 2B and INSAT 2C are geostationary satellites of India. It is a situation in which the effective weight of the body becomes zero, Weightlessness is achieved. Newton’s view of Gravitation. It is denoted by U. Gravitational potential energy U = – GMm / r. The negative sign shows that the gravitational potential energy decreases with increase in distance. The value of G is independent of the nature and size of the bodies well as the nature of the medium between them.
