[1 point] What is the difference between being in a strong gravitational field and accelerating upward?

Answer 1

ane in solution: - Einstein came up with an explanation for why the inertial and the gravitational masses equivalent. He said that experimanting a gravitational field (such as on the surface of the earth.) is equivalent to experimenting in that is located out in space far from any gravitational field. an accelerating elevator Hannah in an I g accelerating elevator Aasson on the Earth A: 8 A: experimentor on the earth bell falls down word with an Hangon - an releases a acceleration g B: Hannah an experimentos in an elevator accelerating upword at g, far from any gravitational field releases ball. She observe that the ball moving downward with an accelerating g Above figure shows one such pair of experiment Aanson and Hannah perform same experiment in seprate small a

a view of the on the earth is far ball and measure g Mannah is rooms, neither of which has outside universe. Aoroson. and Hannah is an elevator that from and gravitational field but is acesterating upword at g Aaron ball drop a as you have probably done in your own laboratory, the downword aceleration of ball and find it is the elevator can not the tell that she is out in space. Her feet feel the normal force of the elevator, and it tells exactly like the normal force of the floor when she is standing the earth Like arson ball she sees the ball fall to the floor of elevator with an elevator g. Because an inertial frame altside the elevator, that in this frame the ball hoverse place. There is not a net force of the ball, So acc according Neuton's first law, the ball remain at rest inertial frame, the floor of the elevator accelerate upword to the ball while the all of this on she drops Q me can view this situation from cue see And, → can we con see

can experiment between being in in an In fact, Einstein said no. be done to tell the experimental difference an accelerating frame and being equally strong gravitations field. This lead to the second postualate of general relativity A gravitational feld is difference to an accelerating refrence frame without gravity second postualate is called the of equivolance, and it leads to mind blowing consequences This principal some
