Consider a satellite that is in geosynchronous orbit around the earth's equator. A geosynchronous orbit is one in Earth which the satellite appears to satellite be stationary overhead for m someone looking up at it from Me a point on the equator – some communications satellites are placed in that orbit because of that apparent "stationary" property. The mass of the earth is Me = 5.98 ×10* kg, and the mass of the satellite m = 100 kg. The radius of the earth is R. = 6.37 × 10°m. The satellite is made of titanium, whose specific heat is 134 J/(kg K) (assume the same for both solid and liquid), the latent heat of fusion is 282.7 kJ/kg, and the melting temperature is 3695K, the boiling temperature is 5828 K. The gravitational constant G = 6.673 × 10" N m²/kg². A. What is the angular velocity of the satellite? В. What is the radius of the orbit of the satellite?
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.
