Which of the following statements is most closely associated with Einstein's general theory of relativity? Mass is equivalent to weight. The gravitational constant has the same value everywhere. Being in an accelerated frame is indistinguishable from experiencing gravity. The gravitational force between any two objects is universal.
Well I'm pretty sure Einstein found out a true fact from what he studied therefore we know A. is at least false due to how Weight can change yet Mass remains the same.
And I'm pretty sure C. is false because I'm pretty sure you feel the same amount of gravity no matter how fast your going.
And I'm not sure about B. or D. so sorry. I can't be any more helpful than that.
5 more questions till im done with my final review sheets! Help anybody?
I'll try my best to help. So go ahead.
1. A baseball is thrown straight upward. Describe the direction and magnitude of the velocity, force of gravity, and the varying air resistance force as the ball rises. Explain whether the net force increases, decreases, or is unaffected by the air resistance force. Repeat for the part of the motion when the ball is at maximum height and the part of the motion when the ball is moving downward.
Well the direction would be straight up and than it will come straight down however it can move off because usually you can't throw straight up and except it to come straight down. I can't think of what the magnitude of the velocity would be. I'm sorry I can't really help on this question.
I wish I could help.
its okay:) thank you! :)
Your welcome although I was of no help really. :( - Thanks for supporting me(If that's what you intend on meaning after saying "Thank you!"). :)
it was A but thank you for your time anyways!
The mass of a person is "constant", while his weight depends on where you are and how much you're being pulled to the center of gravity. (In high places you weight less than in sea-level places, while your mass is the same!) G (NOT g!!!) is the gravitational constant, which determines how much two Newtonian objects interact due to their mass and the distance between them, and is independent of where you are in space. Being in an accelerated frame of reference is very different from experiencing gravity like in earth. For example, in free fall, you're accelerating, but you feel like if you're floating. (For example, an astronaut in the ISS). The gravitational force between two objects really depends on what's around them, and how space-time is around them.
wait , so the answer was A ?!
wikipedia : "According to general relativity, objects in a gravitational field behave similarly to objects within an accelerating enclosure. For example, an observer will see a ball fall the same way in a rocket (left) as it does on Earth (right), provided that the acceleration of the rocket provides the same relative force."
im sure that it is C.
ha ya well maybe my teacher made a mistake.
