Farrell has just begun the astronaut training program at NASA. As part of the program he weighs himself on the surface of the earth and finds that he has a mass of 110 Kg. The mass of the earth is 5.98E+24 kg. a.What is the weight (in Newtons) of the astronaut on the surface of the earth (6370000 meters from the center of the earth)? b.because of his optimal weight and hard work in training, Farrell is chosen to collect data from space around earth and is launched up to twice the earth's radius (double the distance to the center of mass). what is his weight or force of gravity at this altitude? c.Calculate the force of gravity on this astronaut in 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.
