PRESSURE, FORCE AND AREA – PRACTICE QUESTIONS CALCULATOR ALLOWED 1. Find the pressure exerted by a force of 600 Newtons on an area of 30 m2. Give your answer in N/m2. 2. An object is placed on a floor. The area of the object in contact with the floor is 3 m2. The pressure exerted by the object is 15 N/m2.
Pressure is defined as the force applied divided by the area over which it is applied. A gas pressure results from the many collisions between gas particles and a surface.
To calculate pressure, you need to know two things: the force or weight exerted. the surface area over which the force or weight is spread. Pressure is calculated using this equation: pressure = force ÷ area. Example. A force of 20 N acts over an area of 4 m2. Calculate the pressure. pressure = force ÷ area. = 20 N ÷ 4 m2 = 5 N/m2.
pressure has units of a force per unit area—the same as a stress. The value of the pressure at a point is independent of the orientation of any area associated with it, as can be deduced with reference to a differentially small
SECTION. 1. Fluids and Pressure. BEFORE YOU READ. After you read this section, you should be able to answer these questions: • What are fluids? • What is atmospheric pressure? • What is water pressure? • What causes fluids to flow? What Are Fluids? You have something in common with a dog, a sea gull, and a dolphin.
Pressure, Force and Area. Question 1 Express pressure in the terms of force are area, given that force = pressure x area. Question 2. A box rests on the floor. The box has a weight of 15N and the area of the box in contact with the floor is 0.4 2.
The document discusses pressure units and conversions between various units used to measure pressure including pascals, kilopascals, atmospheres, pounds per square inch, millimeters of mercury, and torr.
