Aqa Science P2 5.5 Activity Sheet Answers < iPhone >

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.

State the relationship between depth and pressure in a liquid. A2. Pressure increases as depth increases (because there is more weight of liquid above). aqa science p2 5.5 activity sheet answers

Why does a ship float? A9. The ship displaces enough water so that the upthrust equals its weight. Why does a dam have a thicker base than top

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). State the relationship between depth and pressure 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)

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).
