Pressure 0.0 / 5 ? PhysicsForcesGCSEOCR Created by: emilysworldCreated on: 27-04-19 08:11 What is the equation for pressure? pressure = perpendicular force/area 1 of 9 What is the unit for pressure? N/m2 or Pa 2 of 9 What is the unit for perpendicular force? N 3 of 9 What is the unit for area? m2 4 of 9 Describe snow shoes Weight (force) spread over greater area so pressure is reduced 5 of 9 Describe ice skates Weight (force) acts on a small area so pressure is high 6 of 9 What two things will increase pressure? Smaller area and larger force 7 of 9 What two things will decrease pressure? Larger area and smaller force 8 of 9 What is 2.9mPa in Pa? 2900000Pa 9 of 9
