Satellites: artificial satellites and applicationsAn artificial satellite is a man-made object placed into orbit around a celestial body, primarily Earth.Artificial satellites are launched using rockets or space vehicles.They remain in orbit due to…
Gravitational potential energy, escape velocity, orbital velocityGravitational Potential Energy (U) is the energy possessed by an object due to its position in a gravitational field.The formula for gravitational potential energy is U = -G(m₁m₂ / r), where G is the…
Acceleration due to gravity, variation with altitude and depthThe acceleration due to gravity (g) is the acceleration experienced by an object due to the gravitational pull of the Earth.The standard value of g at the Earth's surface is approximately 9.8 m/s².g…
Newton’s law of gravitationNewton’s Law of Gravitation states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to…
