Fields, directions, and equipotentials

Fields, directions, and equipotentials

Side-by-side diagrams of a positive point charge with outward electric field lines and a point mass with inward gravitational field lines, both with concentric equipotential circles meeting the field lines at right angles

A field is a region of space where an object experiences a force without contact. In an electric field, the direction is defined by the force on a small positive test charge, while in a gravitational field, it is the force on a small test mass.

Step-by-step lessons on Eduqas A Level Physics Electrostatic and Gravitational Fields of Force. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- a minimum of 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.
