Describing motion on one line
Describing motion on one line
Motion along a straight line is called kinematics. When analyzing this motion, you must first choose a positive direction, because movement in the opposite direction will be represented by negative displacement or negative velocity values.
Step-by-step lessons on AQA A Level Physics Motion along a straight line. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
