Exam 36: General Theory of Relativity

If the Sun collapsed to a black hole, Earth's speed in space would

Galileo dropped two balls of different weights and found they accelerated equally to the ground below. Einstein imagined the same result for a side-by-side drop

Strictly speaking, the sum of the angles on a triangle equals 180 degrees

Compared with Newton's theory of gravity, Einstein's theory is

Einstein's theory of gravitation

If you toss a ball "horizontally" from one wall to an opposite wall inside an accelerating spaceship in deep space, defining "up" as the direction of acceleration, the ball will hit

If you move a clock from Earth to the Moon, the clock runs

Accelerate an electron and you produce an electromagnetic wave. Accelerate a massive body and you produce

If a star 100 light-years away explodes, the time for the gravitational waves to reach Earth is 100 years as measured from

If the elliptical orbit of Mercury were more eccentric, its precession rate would be

If the Sun collapsed to a black hole, Earth would

A measuring stick on a rapidly rotating disk will not appear to shrink if it is oriented along the

Inside an accelerating spaceship in deep space, a sideways-tossed ball will

Important support for general relativity came from studies of the precession of the orbit of

You shine a beam of monochromatic light from Earth to an astronaut friend in orbit. The light your friend receives, relative to light from an equivalent source on the spaceship, is slightly

The shortest distance between two points on a curved surface is a

If you shine a flashlight from one wall to an opposite wall inside a spaceship drifting without acceleration far from gravitational influences, the beam of light will travel

If you move in the direction in which gravity acts, an observer at rest sees your watch running

On a giant rotating turntable are two clocks, one at the center and the other at the rim.The clock that runs slower is at

The principle of equivalence tells us that
