What is the correct comparison between the forces in the following question?
An apple falls from a tree because of the gravitational attraction between the¬†earth and the apple. If F1 is the magnitude of the force exerted by the earth¬†on the apple and F2 is the magnitude of the force exerted by the apple on the¬†earth, then
A. F1 is very much greater than F2 B. F2 is very much greater than F1 C. F1 and F2 are equal D. F1 is only a little greater than F2
Gravity causes object to quicken with equal rate. All the more for the most part, free fall with equal rate is the property of gravity. Weight isn't property of gravity. ... As indicated by Newton's second Law of Motion, Force = mass duplicated by the quickening (because of gravity).
Sean Carroll, noted physicist in relativity, likes call this the "Newtonian Equivalency Standard." The supposition is that gravitational mass is identical to inertial mass.
Be that as it may, it shows signs of improvement. Einstein considers a similar polarity , yet thinks of an altogether unique conclusion. He infers that they are not simply equal, but rather a similar thing. This is displayed in great inquiry "is the force because of speeding up in a lift the same as that of the force because of gravity."
Newton said that they are some way or another, without clarification, equal esteemed. Einstein said inertial mass is the same as gravitational mass, in light of the fact that the same are only two methods for taking a gander at a similar thing.
The rest is the historical backdrop of general relativity.
