Astronomers are constantly discovering new planets orbiting nearby stars. In the following scenarios, compare the gravitational force between the planet and its star to the gravitational force between the Earth and the Sun and enter your result as a decimal with no units. (For instance, if the gravitational force between the planet and the star is 1/4 the gravitational force between the Earth and the Sun, enter 0.250) A planet that has a mass 14.92 times that of the Earth is orbiting a star that has the same mass as the Sun. The planet orbits at an average distance of 1.00 AU. How does the gravitational force between this planet and its star compare to the force between the Sun and the Earth?
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.
