Experiments involving Newton's second law.hey can anyone help please.............I have physics practical exam AS. Can anyone guess about the questions or suggest me the topics to prepare?
why do we use travelling microscope does any1 know?
you are asking question from paper 3 ....there are uncertainty questions in paper 2 as well !http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s10_qp_31.pdf
Q.2 part (c) (iii)

Q.2 part (c)

Q.2 part (c)
In both cases it has been roundedhttp://olevel.sourceforge.net/papers/9702/9702_s12_ms_22.pdf Q1 part 2 when we add up % error it come 8.5 why it is 8.6 wriiten in ms and als in Q2 when we caculate the speed it come 12.986 why it is written 12.99 and then also used in the next part as 12.99 .12.99 is 3s.f?
Well the uncertainities in paper 2 are very easy....I wanted help with this ppr 3 thingy...btw thanks for ur time...you are asking question from paper 3 ....there are uncertainty questions in paper 2 as well !
the questions you have asked are part of the whole experiment ....its not possible for me to know the timing recorded unless i do the expt my self !!
please go through some uncertainty in paper 2 ......i will try to help you out as much as i can
you should consider initial vertical velocity ut when calculating for s .....and the way to do that is in the msAOA

Q2(a)(ii) ...... am getting different answers by 2as = v^2 - u^2 and by using s= ut + 0.5at^2 ??
reason? anywhere am going the wrong way please inform
thank you
well if you do think uncertainty in paper 2 is easy then paper 3 would be easy too .......anyhow uncertainty of a device is least value it can measure ....welcome for ur understanding!!Well the uncertainities in paper 2 are very easy....I wanted help with this ppr 3 thingy...btw thanks for ur time...
the thing is that in ppr 2 the readings are given and in ppr 3 we have to calculate them from the instrument being used..well if you do think uncertainty in paper 2 is easy then paper 3 would be easy too .......anyhow uncertainty of a device is least value it can measure ....welcome for ur understanding!!
by placing the set square adjacent to ruler and seeing that it's one side is parallel with the ruler and other with the table on which the ruler is placed..any1 know the detailed use of the set square. in marking scheme it is given: write detailed use of set square. do u know when measuring height how do we tell how the setsquare is used to check if the ruler is vertical?
K.e=1/2 mv^2hey can anyone help me with ON'06/02/1.c.ii and 2.c.iii
