What is upthrust? A8. An upward force exerted by a fluid on an object immersed in it (caused by higher pressure at the bottom of the object than at the top).

Explain why your ears ‘pop’ during takeoff in an aeroplane. A7. Outside air pressure decreases rapidly at high altitude; pressure inside the ear is initially higher, so air pushes out until equalised. aqa science p2 5.5 activity sheet answers

Here are the for a typical AQA GCSE Science P2 – 5.5 Activity Sheet (topic: Pressure and Pressure Differences – often part of the Particle Model of Matter or Forces unit, depending on the specific sheet). What is upthrust

Why does a dam have a thicker base than top? A3. Pressure increases with depth, so the base must be thicker to withstand the greater force. Explain why your ears ‘pop’ during takeoff in

Calculate the pressure at the bottom of a 5 m deep swimming pool. (Density of water = 1000 kg/m³, ( g = 10 ) N/kg) A4. ( P = h \rho g = 5 \times 1000 \times 10 = 50,000 ) Pa (or 50 kPa)
