Find out about liquids and gases, atmospheric pressure and particle collisions with this guide to pressure in fluids for KS3 physics students aged 11-14 from BBC Bitesize.
To calculate pressure, you must use the equation: Pressure = force ÷ area. The units are: Pressure: N/m 2. Force: N. Area: m 2. 1 N/m 2 is equal to 1 Pascal (Pa). Area and pressure. The larger the area in contact with a force, the lower the pressure.
Pressure is a measure of how concentrated a force is. Pressure = force ÷ area. Pressure is measured in newtons per square metre or per square centimetre. Another name for newtons per square metre is the pascal (Pa).
These 3 quantities are linked by the following formula: pressure = Force / Area of surface. or, p = F / A. where, p is pressure in newtons per metre squared, N/m 2. F is Force in newtons, N and A is Area in metres squared, m 2. So, let's say our ship weighs 100,000 N and the surface area of the hull is 100 m 2; what is the water pressure acting ...
Students can use this worksheet to practise using the pressure equation. A support sheet is also available which provides the pressure equation, any rearrangements of that equation which are necessary and also breaks down multifaceted questions.
Calculate the pressure. Step 1: Use the formula: Pressure = Area Force Step 2: Substitute the correct values: Pressure = 2 5 Step 3: Complete the calculation: Pressure = 2 5 = 2.5. Pressure = 2.5 N/m 2
