Density equation
Density = Mass / Volume
Density symbol equation
p
= m / v
Define density
The ammount of mass per unit volume
How to find density of regular object
- Find mass - use mass blance (tare/zero) [in kg]
- Find volume - V = l x h x w, use ruler [in m]
- Density eqution
How to find density of irregualr object
- Volume displacement - use eureka can
- Lower slowly until fully submerged
- Use measureing cylinder for displaced water
- Find mass - use mass balance (tare/zero) [in kg]
- Use density equation
Pressure equation
Pressure = Force / Area
Pressure symbol equation
p = F / A
