Ms Q R Mp (b) How do the tangential speeds of planets B and C compare to that of Planet A? In a clear, coherent paragraph-length response that may also contain equations and/or drawings, provide claims about why the tangential speed of Planet B is either greater than, less than, or the same as that of Planet A, and why the tangential speed of Planet C is either greater than, less than, or the same as that of Planet A. MsQR System A System B Three different planet-star systems, which are far apart from one another, are shown above. The masses of the planets are much less than the masses of the stars. In System A, Planet A of mass M, orbits Star A of mass M, in a circular orbit of radius R. In System B, Planet B of mass 4Mp orbits Star B of mass M, in a circular orbit of radius R. In System C, Planet C of mass M₂ orbits Star C of mass 4M, in a circular orbit of radius R. 4Mp AMS System C R Mp

Gravitational force

In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.

Acceleration Due to Gravity

In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
