How do clock hands defy gravity?
You are correct, the clock would need more force to raise the hands than to lower them, and even if the difference is very VERY small, there would be a difference. However, there are two issues here: The first is that the difference would be very small for a wall clock – it could add a second or two an hour but that would average out over each hmo totThe second is – and this would also apply to really large clocks – that the design of a synchronous motor is such that when the resistance to movement increases, the motor’s force increases. It is designed to move at a certain speed, and will – within its capabilities – increase the force needed to achieve that, as it is required. And in fact, for very large clocks, there is sometimes a counterbalance for each hand on the inside of the clock.
