This morning at 8:17 PST, a Houston-based startup company named Axiom-1 Space launched an all-private astronaut crew on a SpaceX Falcon-9 Rocket to fly to the International Space Station (ISS). The International Space Station would weigh 925,000 lbs. on earth a) Determine the mass of the ISS in kg . b) If the ISS orbits the earth at a height of 4.2 x 10^5 m above earth's surface, draw a sketch of the scenario and determine the distance ( in meters) between the center of gravity of the earth and the ISS given the radius of the earth is 6.4 x 10^6 m. (Round answer to the nearest tenth) c) Determine the gravitational force of attraction between the earth and the ISS given earth's mass is 6 x 10^24 kg . d) Determine the tangential velocity of the ISS. (Hint: Recall your equation for F(centripetal) setting it equal to your F(gravitational) just determined in part c) and solve for the tangential velocity of the ISS.
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.
