Gravity, mass and weight
Gravity, mass and weight
Gravity is a force between masses. Near Earth, the gravitational force on an object is called its weight, and weight is measured in newtons.
Step-by-step lessons covering Edexcel A Level Physics Gravitational fields and Newton's law 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.
