MJ16 P52 Q2 Paper 5 Tutorial | A2 Practical | CAIE A Level 9702 Physics

9702/52/M/J/16: Tutorial on how to complete the written practical. #9702s16p52 #A2inversePowerP5Q2 #Lv1 MJ16 P52 - FULL SOLVED past year. Intro 0:00 - Easy vs Hard questions Experiment intro 0:39 - Reading the question & Identifying constants Linearizing 1:53 - determine expression of gradient Table: 3:02 - completing the table - transfer of headers & prefixes 4:11 -finding absolute uncertainties for table values (Method 1: Identities) 12:13 - (Method 2: Max Min Values/half the range.) 15:18 - Comment on marking & errors. plot graph & error bar 17:15 - DOUBLE CHECK your axes & comments on common errors. 18:36 - ODD scales?? 19:11 - plotting begins? 1st reading. 19:53 - NO inbetween plots, how to round. 21:47 - First error bar drawing, BUT TOO SMALL. 23:34 - is there a problem??! 24:45 - corrected plot. 28:11 - second plot & error bar for 6th reading Drawing Best Fit & Worse fit line 29:17 - Completed graphs - discussion about error bar. 30:18 - Best fit line - all points MUST be close, will not have anomalous. 30:38 - How to Worse fit line. [Worse fit line MUST pass ALL error bars] Finding gradient and its uncertainty 31:36 - gradient Calculations of resistivity, resistance & their uncertainties 33:56 - resistivity 36:00 - uncertainty in resistivity 36:38 - Resistance of new wire. & its uncertainty How to: Written Practical | #A2physicsP5    • Paper 5 A2 Physics 9702 Written Practical ...   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
