Fields, directions, and equipotentials
Fields, directions, and equipotentials

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 covering Eduqas A Level Physics Electrostatic and Gravitational Fields of Force for A Level Physics. Each lesson works through exam-style questions in Component 1, Component 2 and Component 3 format. 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.
