Vector & Scalar Quantities

All quantities in physics are either vectors or scalars
- A scalar quantity describes a magnitude only, e.g. a room temperature of 16° C
- A vector quantity describes both magnitude and direction, e.g. a large pot of rice exerts a force of 40 N downwards on a cooker
The table below summarises the vector and scalar quantities related to moving objects

Absolutely brilliant, both my girls used it for A levels and GCSE. It's saves on paper copies, also beneficial exam questions ranked from easy to hard. It's removed a lot of stress from the exams.
