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.
Common misconception
Pupils may not have encountered the moment equation in physics.
Pupils might need extra support substituting values into the equation.
