Motion quantities and sign convention
Motion quantities and sign convention
In SUVAT problems we model motion in one straight line, so the first job is to choose a positive direction. Once that is fixed, motion the other way is negative rather than "wrong".
Step-by-step lessons covering Edexcel A Level Physics SUVAT and motion graphs for A Level Physics. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
