Pressure Flashcards
1
Q
What does pressure tell us?
A
How concentrated a force is.
2
Q
What is pressure measured in?
A
Pascals (Pa)
1 Pa = 1 N m-2
3
Q
Pressure equation.
A
Pressure = Force (in N) / Area (in m2)
P = F/A
4
Q
Why do camels have large flat feet?
A
- To spread thier weight over a large area
- Reduce the pressure they exert on the ground
- Means they are less likely to sink into the sand
5
