Last updated: 15/11/2023
A comprehensive KS4 physics PowerPoint lesson with 7 class tasks (with answers) on pivot, load and effort.
Includes a range of diagram labelling tasks, extra challenges for early finishers or higher attaining students and exam-style calculations, as well as supporting videos.
An example task from the PowerPoint lesson:
Principles of moments
If you were to calculate the moment for each person on opposite sides of the see-saw and they were equal, we would say the see-saw is balanced. We call this the principle of moments.
When an object is balanced about a pivot, then: anticlockwise moment = clockwise moment
