MJ15 P33 Q1 Hanging Card | AS Practical Paper 3 | May/June 2015 | CAIE A Level 9702 Physics

9702/33/M/J/15: In this experiment, you will investigate how the position of a suspended card varies with the distribution of masses attached to it. This is based on the idea of center of mass! #9702s15p3 #ASequilibriumP3Q1 0:25 Lab equipment check 3:09 Punching a hole using the nail 3:33 Mass of Card, C 5:08 Measuring 1cm for the hole 8:07 Poking the hole (be careful!) 10:48 How to Retort stand boss & clamp 11:56 How to set-up nail & card 13:08 How to plumb-line 14:30 Making your mark on the card 16:10 Repeat using the other hole. 17:30 Measure first y 19:24 Adding masses to card (Independent Variable) 25:13 My dudes, My ladies, we are finally ready 26:00 Marking ALLLL The other points 36:20 X marks the spot - find all the centres of mass (Dependent Variable) 42:12 Label and measure ALLLLL the y. 44:00 Results here 45:05 How to table 48:37 BONUS - using CALC in the calculator 49:40 Ta-dah, the graph & criterion 53:00 How to gradient 55:29 How to y-intercept 56:53 Graphical Analysis in finding A and B #ASphysicsLab Paper 3 Playlist:    • Paper 3 AS Physics 9702 Lab Practical Skills   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
