CAIE IGCSE Physics EXTENDED 1.5.1.12 Circular motion caused by a force
Practise analysing circular motion by identifying the inward resultant force and how speed, radius and mass affect the force needed.
How this is tested
- draw the resultant force arrow towards the centre of a circular path
- explain why constant speed in a circle still needs force because direction changes
- predict that a smaller radius or larger mass needs a greater inward force
