Visualising gravitational fields

Visualising gravitational fields

Field lines comparing a uniform gravitational field with parallel downward arrows and a radial gravitational field around a planet with arrows toward the centre and lines spreading out with distance

A gravitational field is a region where a mass experiences an attractive non-contact force. Because the field itself is invisible, we draw field lines to show what would happen to a small test mass.

Step-by-step lessons on AQA A Level Physics Gravitational field strength (A-level only). 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.
