HEY everyone please very important for the practical, the last 2 questions always state 4 sources of errors and improvements, please can someone help me with this
Answers are in the Mark Schemes here: http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/
Here are some common answers..
Limitations:
- two results not enough
- measurement of radius/distance/etc. not accurate
- difficult to stop stopwatch at correct moment
Improvements:
- take more readings and plot a graph
- use vernier caliper/travelling microscope
- record using video camera, play in slow motion & use a timer
