Question 11 • Physics

Which best explains a difference between Einstein’s general theory of relativity and his special theory of relativity?

Answer

His general theory applies only to uniform motion, but his special theory includes uniform and accelerated motion.

His general theory includes uniform and accelerated motion, but his special theory applies only to uniform motion.

His general theory includes uniform and accelerated motion, but his special theory applies only to accelerated motion.

His general theory applies only to accelerated motion, but his special theory includes uniform and accelerated motion.

Explanation

Special relativity describes motion in inertial frames, where objects move at constant velocity (uniform motion). General relativity extends the theory to include accelerated motion and gravity, while also describing uniform motion. Therefore, choice A correctly states the difference.
