Mark true (T) or false (F) fo the statements.
( ) Strictly speaking, Special Relativity is NOT compatible withgravitational phenomena.
( ) The Newtonian theory of gravitation is not covariant, likerelativity, because space and time do not receive the same kind ofmathematical treatment in its formalism.
( ) Consider a small spaceship traveling far from any star. Thephysical phenomena felt by the crew as a result of the constantoperation of the ship's propulsion are indistinguishable from theeffects of a gravitational field.
( ) In Einstein's General Theory of Relativity there is no force ofgravity. The curvature of spacetime and the trajectories followinggeodesics replace this force and explain the gravitationaleffects.
( ) Tidal effects, felt by a mass along its length, are directlyrelated to the curvature of spacetime in that region occupied bythe mass.
( ) In the general case of a curved space, geodesics play the samerole as straight lines do in flat (Euclidean) space.
( ) The basic laws of General Relativity, contained in Einstein'sfield equation, can be expressed in colloquial language as: "Mattertells spacetime how to curve and, in turn, spacetime tells matterhow to move."
( ) The “equivalence principle” says that for a region of space aslarge as desired, the effect of an accelerated frame of referencecannot be distinguished from the effect of a gravitationalfield.
( ) Imagine a trip to the Moon where a small ship, devoid of apropulsion system, is launched by a large cannon, as in the 19thcentury fiction book “From the Earth to the Moon”, by the writerJules Verne. In such an inertial journey, according to physics, thecrew inside the spacecraft would feel, in the first phase of thejourney, a gravitational force pointing towards Earth. This weightfelt by the crew would decrease until, in the final phase of thevoyage, its direction would be reversed, starting to point to theMoon.
( ) The pace of a stationary clock at a great distance from Earthappears to run slower than the pace of an observer on the Earth'ssurface, due to weaker gravity at this high altitude.
( ) The tidal forces felt by a given star do not depend on itssize.
( ) General Relativity includes Special Relativity as a particularcase, but does not include Newtonian theory of gravitation as aparticular case.
