CAIE IGCSE Physics Weight as Gravitational Force

Practise defining weight as gravitational force, identifying it in force contexts and explaining why its magnitude changes with mass or gravitational field strength.

Exam points

state that weight is the gravitational force acting on an object with mass and is measured in newtons
identify weight as the downward force that stretches a spring or acts on a supported object
explain weight changes through mass or local gravitational field strength while separating it from mass

Fig. 2.1 shows an electric tumble dryer used to dry wet clothes.

Fig. 2.1

The drum of the tumble dryer rotates, lifting up the wet clothes which then fall down through the hot air.

Name the force that causes the clothes to fall down.
