MJ12 P31 Q2 Data: Friction up an Incline | AS Practical Paper 3 | Cambridge A Level Physics

9702/31/M/J/12: In this experiment, you will investigate how the force required to pull a block up an inclined plane depends on the angle between the inclined plane and the bench.
#9702s12p3 #ASforcesP3Q2
We will learn how to use a Newton Meter to measure the force needed to over come the friction between an inclined plane and a block.

i just watched this the day before my exam and I'd like to say you just saved my grade because our teacher didn't teach us this, so honestly thank you so much you're a life saver!!!😁

hi

[@sufyanbutt12]

so question will be like this type.

[@vrajshah3043]

Yeah

[@samsyy-601]

@@vrajshah3043 what are the common limitations and improvement for experiments like this????
plss helppp

​​​​@@samsyy-601 tell me your reddit i will send you photo that has impr and errors related to it

[@wait9959]

During my practical,i measured the angle and wrote my answer down. When i got my paper back,i got marked wrong and my sir wrote "where is the evidence of the angle." Does this mean i have to measure the angle 3 times and cal an average?

[@maven8470]

teacher dumb question but why arent we measuring the angle from the centre of the protractor meaning the small circle?

[@hassanrehman7745]

i think it was prolly a mistake by the teacher
