Textbook Question
Chapter 6, Problem 10A
Distinguish between force and pressure.
Expert Solution & Answer
To determine
To explain: The difference between force and pressure.
Explanation of Solution
Introduction:
Force is push or pull to an object. For a constant force an increase in area of contact decreases the pressure on an object.
The amount of force per unit area is pressure. Pressure is measured in Newtons per square meter. Pressure is scalar quantity. Pressure acts on the surface of an object. Pressure cannot change the velocity of the object. Pressure is measured by an instrument called a barometer.
Force is measured in Newton. Force is a vector quantity. Force acts on the edges, surface, faces and sides of an object. Force changes the velocity of an object.
Conclusion:
Force is push or pull. Pressure is force per unit area.
