Many people mistakenly believe that astronauts that orbit the Earth are "above gravity." Calculate the acceleration due to gravity (g) for space shuttle territory, 200 kilometers above the Earth's surface. Earth's mass is 6 x 1024 kilograms and its radius is 6.38 x 106 meters (6380 kilometers). Your answer is what percentage of 9.8m/s2?
(Can you help me break it down in a way that I could understand and calculate?)
Why is Newton's version of Kepler's third law so useful to
astronomers?
It is the only way to determine the masses of many distant objects.
O It tells us how rapidly a planet spins on its axis.
O It explains why objects spin faster when they shrink in size.
O It tells us that more-distant planets orbit the Sun more rapidly.

- Newton showed that the periods and distances in Kepler’s third law depend on the masses of the objects.

Give your answers in years.arrow_forwardYou may have an image of Sir Isaac Newton sitting under a tree and after being hit on the head by an apple he suddenly "discovered" the Law of Universal Gravitation. In fact, the theory was a result of years’ worth of research, which in turn was based on centuries of accumulated knowledge. He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?arrow_forwardMany people mistakenly believe that astronauts that orbit the Earth are "above gravity."
