Physics - 2009 winter paper doubt PLEASE PLEASE HELP !!!
« on: February 28, 2010, 03:50:54 pm »
look at question 1 PHYSICS PAPER 3 2nd variant


How on earth do you measure the amplitude of oscillation ??? How could can CIE ask such a question when we have never done this before ?

What is the underlying concept ??


-----------------------------------
The new pattern in PAPER 3 is to always ask something experimental.

SO please tell me a list of experiments/ experimental concepts that I should be aware of for BOTH paper 3 & 6

I think you should measure the angle between the vertical to the fixed point and B.
Do this with a large protractor fixed to a board behind the swinging weight.
The weight will be moving v slowly at the endpoints and should be easy to measure.

Im sorry but dont understand what that has to do with the amplitude of oscilltion. Could u please explain WHAT amplitude of oscillation is







I thought you would measure the distance between the fixed point and A. Is nt amplitude the maximum displacement ?

It is the largest distance from the centre or rest or hanging point
you can also callit an angle in the case of a pendulum
