New GCSE AQA Physics lesson on ' Centre of Mass' written in line with new AQA Physics specification. All questions provided with answers within power point.
Starter simply looks at balancing object on one finger and how intuitively we can know how to do this. Then stability of different shapes is reviewed and again highlighted how we can assess whether something will be stable or not. The physics of this is then applied in terms of centre of mass. The technique to find the centre of mass for a symmetrical shape is detailed and practices with questions.
Suspended equilibrium and centre of mass is shown using a hanging bird cage and can also be demonstrated in class with a simple mass and string. Then an experiment is outlined to find the centre of mass of irregular shapes.
Centre of mass it then related to real life contexts for practice exam questions.
Lesson Objectives:
- Explain what is meant by centre of mass.
- Find the centre of mass for a simple symmetrical object and explain this position.
- Find the centre of mass of an irregular shaped object.
- Apply the principle of centre of mass to real-life problems.
