Chapter 3 | Pressure Flashcards
1
Q
Pressure is?
A
It’s a force applied perpendicularly to a surface
2
Q
What are the two things in pressure that we can measure?
A
- Force : measured in Newtons (N)
- Area : measured in meters²
1m x 1m = 1m²
3
Q
What unit is used for pressure?
A
The unit is called “Pascal” (Pa), and it’s equivalent to Pressure
Pressure = Force
———
Area
Pa = N

m²
4
Q
What happens if we increase the force?
A
The pressure will increase
5
Q
What happens if we increase the area?
A
Pressure will decrease
6
Q
Give examples where people use surface area to their advantage:
A
- Needles (Small Surface Area)
- Thin Ice (Spread Out)
