Density, Pressure and Upthrust 0.0 / 5 ? PhysicsDensity and PressureASOCR Created by: JoshuaEmery2017Created on: 27-11-17 20:48 What is Density ? Density is Mass per Unit volume 1 of 7 What is Pressure ? Pressure is the amount of force applied per unit area 2 of 7 What is density measured in ? Measured in Kg m^-3 3 of 7 What is pressure measured in ? Measured in N m^-3 4 of 7 What is Upthrust (in fluid) ? Upwards force that fluid exerts on an object that is completely or partially submerged in fluid 5 of 7 Why is their upthrust in water ? Due to the bottom and top of the object being at different depths therefore different pressures it causes an upwards thrust. 6 of 7 What is Archimedes Principle ? When a body is completely or partially submerged in a fluid, it experiences upthrust equal to the weight of fluid it has displaced. 7 of 7
