Question

Two space ships are travelling in the same direction. An astraunaut in first ship drops a coin and finds that the coin stays at rest. An astraunaut in second ship drops a coin and finds that the coin starts moving in forward direction with an acceleration of 2 m / s 2 . Assume that the coin is uncharged and the whole system is in gravity free space.

TestHub · Accepted Answer

Ship 1: the coin stays at rest relative to the ship, so the ship has no acceleration. It is an inertial frame.

Ship 2: the coin (no force on it) accelerates at $2 m/ s^{2}$ relative to the ship, so the ship is accelerating and is not an inertial frame.
