Work done and direction

Angled pulling force on a box showing the horizontal component that does work

Work done is the energy transferred when a force makes its point of application move through a displacement. For a constant force parallel to the motion, W=FsW = FsW=Fs, so 1 J=1 N m1 \, \text{J} = 1 \, \text{N m}1J=1N m.

Step-by-step lessons on Edexcel A Level Physics Work, energy and power. Each one builds up to exam-style questions. 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.
