Make up a multiple-choice question to check a classmate’s understanding of the principle of equivalence.
Solution 39E Step 1 The principle of equivalence states that the gravitational mass and the inertial mass are equivalent. This means that the mass that causes the gravity and the mass which causes the inertia of the object are equivalent. So the force that is experienced by a mass in the local gravitational field is same as the pseudo force experienced by the mass in a non-inertial (accelerated) frame. In other word suppose a mass m is earth’s gravitational field, it will experience the force of F g mg Now if the mass is in some accelerated frame, which is accelerating with the acceleration g , then the forces are same and there is no way to distinguish between them by doing some experiment in the local frame.
