No, the wristwatch will not give correct time during free fall from the top of a tower. This is due to the effect of gravity on the watch's functioning and the relative motion between the watch and the person in free fall.
1. Gravitational Time Dilation: According to Einstein's theory of general relativity, gravitational fields can affect the flow of time. In the presence of a strong gravitational field, time runs slower relative to a weaker gravitational field. As the person in free fall descends from the top of the tower, they experience a decrease in the strength of the gravitational field. This means that the wristwatch, which is subject to the same gravitational effects, would also experience a slower passage of time compared to someone at a higher altitude.
2. Relative Motion: Additionally, the person and the wristwatch are both in a state of free fall, which means they are accelerating downward at the same rate due to gravity. In this scenario, the person and the watch are in free fall together, so there is no relative motion between them. However, if the person and the watch were to have a relative motion (e.g., if the watch were detached and moving independently), the motion could affect the timekeeping accuracy of the watch.
In practical terms, the wristwatch's timekeeping mechanism relies on a consistent gravitational field to operate accurately. During free fall from a tower, the varying gravitational field and the acceleration due to gravity would disrupt the normal functioning of the watch, and it would not give correct time until the person lands and returns to a stable gravitational environment.
It's worth noting that this effect is only significant in extreme scenarios involving very high towers or objects in strong gravitational fields, such as those near massive celestial bodies like black holes. For everyday experiences and falls from reasonable heights, the difference in timekeeping would be negligible and not noticeable.
