Lesson details
Key learning points
- A muscle attached to a bone exerts a force on the bone when the muscle contracts, which makes the bone move.
- Biomechanics is the study of this movement.
- A moment is the turning effect of the force when a bone pivots at a joint.
- The size of the moment when a bone pivots at a joint can be calculated.
Keywords
Muscle contraction - Muscle contraction is the shortening of muscles.
Force - A force is a push or a pull that acts on an object.
Biomechanics - Biomechanics is the study of how the body moves.
Moment - A moment is the turning effect of a force.
Pivot - The point around which an object can rotate is a pivot.
Common misconception
Pupils may not have encountered the moment equation in physics.
Pupils might need extra support substituting values into the equation.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
