Density And Pressure Flashcards
1
Q
What is the equation for weight
A
Weight = mass x gravity. E.g. A 100g bag of sugar on earth has a weight of 1kg
2
Q
What is the equation for pressure?
A
Pressure = force / area. If there is a small area, there will be much pressure, like in an egg slicer.
3
Q
How do you work out pressure in fluids?
A
Pressure = density x gravity x depth
Pressure at a point in a gas or liquid acts equally in all directions
4
Q
What is the equation for density?
