Answer no. 1 ( a&b) and no. 2 please 1. Assume that a satellite orbits Earth 225 km above its surface. Given that the mass of Earth is 5.97 x 10^24 kg and the radius of Earth is 6.38 x 10^6 m, what are the satellite's orbital speed and period? a) Suppose that the satellite in Sample Problem number 1 is moved to an orbit that is 24 km larger in radius than its previous orbit. What would be its speed be? b) Is this faster or slower than its previous speed? 2.Two objects are attracted to each other by a gravitational force F. if one mass is doubled and the other is tripled without changing the distance, what is the new gravitational force between the objects in terms of F? a. 4F b. 9F c. 6F d. 1/9F
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.
