# Lakhmir Singh Solutions Class 8 Science Solutions for Exercise in Chapter 11 - Force and Pressure

Question 64 Exercise

a) Define pressure. What are the relation between pressure, force, and area? State the units in which pressure is measured.

b) Explain why school bags are provided with wide straps to carry them?

a) The pressure is defined as force acting per unit area. Different units of pressure are Pascal, Newton per square meter, atmosphere, torr, bar, and meters seawater.

The relation between pressure, force, and the area are:

P = F/A

b) School bags are provided with wide straps to carry them because the force gets distributed throughout thereby reducing the pressure.

"hey kids welcome to leto q a video i am vineeth your lido tutor glad to bring you this question on your screen so define pressure what is what are the relation between pressure force and area state the units in which pressure is measured so the pressure is defined as the force acting per unit area pressure is the force acting per unit area the units of pressure are different units of pressure are pascal newton per square meter newton per square meter then we have tor bar and meter sea water tor bar and meters seawater and the relation between pressure the relation between pressure force and area is pressure is equal to force per unit area now the second one explain why school bags are provided with white straps to carry them so b school bags are provided with white straps because the force gets distributed through thereby reducing the pressure so due to white straps the force gets distributed and pressure is reduced thus school bags are provided with white straps provided with white straps to carry them if you still have a doubt please leave a comment below do like the video and subscribe to our channel i'll see you in our next video until then bye kids keep practicing"
