hi everyone,
i often wondered myself the physics behind the sand clock..
now,imagine a 1 hour sand clock or hour glass (the sand in upper part takes an hour to settle down completely).if anyone knows the physics of the sand clock,kindly let me know the following:
1) How much is the effect of gravity on the sand particles inside the clock ?
2) Normally the sand clock is kept vertical to the ground plane.If the clock is tilted to some extent making an angle to the ground,will the sand clock measure the time as usual (1 hour) or does time vary ?
