Forces 1: bumper set of equations
A set of 230 physics equations – with answers – for practice and revision for GCSE combined science and physics students.
Includes a range of calculations and equations for students to practise in the following topics:
- Weight and mass
- Resultant forces
- Work done
- Moments
- Pressure
- Pressure in fluids.
There are reminders of how to complete all the equations at the beginning of each topic, with sets of 10 equations to complete.
Answers are included to help teachers and/or for self or peer marking in class.
Share with students for independent practice or revision, or complete a set of 10 calculations in class a quick learning check or assessment task.

Moments
moment of a force = force x distance
M = F d
(You should be able to recall and apply this equation.)
