Define pressure. What is the relation between pressure, force and area? State the units in which pressure is measured.
Answers
Answer:
Pressure is an expression of force exerted on a surface per unit area. The standard unit of pressure is the pascal (Pa), equivalent to one newton per meter squared (N/m 2 or N. ... It is the force of thrust per unit area.
Pressure
Explanation:
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Various units are used to express pressure like N/m2, kg/(m·s2), or J/m3. The SI unit of pressure, the pascal (Pa), for example, is one newton per square metre (N/m2). Similarly, the pound-force per square inch (psi) is the traditional unit of pressure in the imperial and US customary systems.
Pressure = Force / area. Pressure is directly proportional to force and inversely proportional to area.
