Chapter 6 - Pressure Flashcards
What is the formula for working out pressure?
Force / area
Pressure is a force…
Acting on a certain area
The bigger the force…
The greater the pressure
The greater the area…
The smaller the force
Why is a person more likely to leave a mark on the floor wearing stilettos than trainers?
Their force is spread over a greater area with the trainers therefore they exert less pressure on the floor
What is pressure measured in
N/m2 or Pa (pascals)
Why do solids have high densities?
Because they are tightly packed in terms of their atoms or molecules
