AQA GCSE Physics Pressure in Fluids Upthrust and Atmosphere Worksheet
AQA GCSE Separate Physics pressure worksheet with answers. Apply fluid and atmospheric pressure, interpret evidence and tackle the correct tier upthrust tasks.
What is covered
Questions and skills covered
The worksheet contains 8 pages of printable questions. A separate 8-page solutions PDF makes it easy to mark, review or share answers after the activity.
- p=F/A
- Normal force
- Rectangular window area
- cm² to m² and kPa to Pa conversions
- Average density of sealed objects
- Pressure versus force comparisons
- Inside-outside window pressure difference
- Atmospheric pressure via particle collisions
- Atmospheric density and weight of air above with altitude
- Higher vertical depth below surface
- Higher p=hρg and depth rearrangement
- Higher total versus liquid-only pressure
- Higher liquid-density comparison
- Higher top-bottom pressure difference and upthrust
- Higher initial sinking force balance
- Higher floating with larger same-weight sealed collar
About this activity
A reservoir team checks inspection-pod windows, a flotation collar and weather stations, using evidence rather than treating pressure as a force.
Before you start
After teaching pressure/area, density and atmosphere. Higher also needs liquid pressure, upthrust and floating/sinking. All conversion factors needed are supplied.
A question from the worksheet
Question4(e), pupil page4
Outside pressure120000Pa, inside100000Pa, windowarea0.020m²: determine the net window force.
Show the answer
Difference20000Pa; net force400N inwards.
Common error: Using total outside pressure for a net load, dividing cm² by100 rather than10000, or saying a floating object has no weight.
