NAGALAND Class 11-science Physics Gravitation
Law of GravitationState Newton's Law of Gravitation and quantify acceleration due to gravity. Discuss variation of acceleration due to gravity with height and depth.
Gravitational Potential EnergyThe gravitational potential energy of two masses separated by a distance r: U= (G.m1Xm2)/r^2. The potential energy is never positive; it is zero only when the two bodies are infinitely far apart.
Kepler's Laws and SatellitesStudy of the Kepler laws governing motion of planetary bodies. Define a satellite, geostationary satellites and understand the meaning of weightlessness
