PHYS 1P22 Lecture Notes - Lecture 6: Drinking Straw, Altimeter, Snowmobile
Document Summary
It hurts when the sharp point is on the hand than. Objectives: know and use the relationship: when the blunt one is against the hand. The same book is being supported therefore equal pressure = force / area p = f / a amount of force being applied. From the two activities above we can conclude that pressure exerted on surface depends on: pressure difference = height density g p = h g: introduction. Using your thumb, push a thumb tuck pin into a soft board. Using an equal amount of force try driving your thumb into the board. You may not make it to do the second part. The small point in the pin concentrated the force on a small area hence it easily gets into the board. This is the case between a sharp and a blunt knife. Pressure can be determined using the following relationship: The si unit for pressure is pascal (pa)
