Question

what is angular momentum and central force in kepler's third law?

Answer 1

Central Force Motion: Kepler's Laws. When the only force acting on a particle is always directed to wards a fixed point, the motion is called central force motion. This type of motion is particularly relevant when studying the orbital movement of planets and satellites. The empirical law is arised from conservation of angular momentum. When the planet is closer to the sun, it moves faster, sweeping through a longer path in a given time
