Why do you get a more accurate measurement of the time that it takes a
ball to fall using timing gates rather than a stopwatch?
plz justify your answer
Answers
Answer:
Step-by-step explanation: Actually both technique are good enough but when we deal with the complex time at deeper level quantum physics says that time is different for different objects it could delay for one to other or can be the same for both it is relative indeed ,now the time gate technique
is used in place of stopwatch because stopwatch's time can be rongh .
Answer:
see below
Step-by-step explanation:
On average hand timing using stopwatches results in errors of up to 10%
Depending on the mass of the ball and the distance it falls, the time taken to fall could be small, which then requires a higher precision on the value recorded. Thus a stopwatch would be ineffective.
On the other hand, timing gates use beams and the assumption with timing gates is that, if the beam breaks for a fraction of a second, it means an object (say, the ball) has passed that exact distance at that moment in time. Therefore its precision is quite high. Also, it improves the experipental conditions whereby the timing method is always the same hence allowing for repeatitions.
