Edexcel A-Level Physics Centripetal Force Requirement

Practise Edexcel A-Level Physics centripetal force by explaining how resultant forces maintain circular motion in real contexts.

Exam points

explain circular motion as a resultant force directed towards the centre of the path
analyse vertical-circle forces where tension, weight or reaction changes between top and bottom
use lift components or inward forces to explain banking, orbiting or passenger motion

[Maximum number: 4]

An aeroplane flies in a horizontal circular path whilst waiting to land at an airport.

The aeroplane flies in a horizontal circle by tilting to one side in a movement called 'banking'.

The aeroplane creates an upwards lift force, which acts in a direction perpendicular to its wings.

The diagram shows this lift force when the aeroplane is banking.
