Physics: Density and Pressure

What is the equation to calculate density?

p = m / V (Density = mass / volume)

What are the measures (symbols?) for density?

kg/m^3 or g/cm^3

How do you find the volume of a irregular solid?

Use the displacement of water from before adding an object and then after. (Volume after - volume before)

What is the equation to calculate pressure?

p = F / A (Pressure = Force / Area).

What are the measures (symbols?) for pressure?

N / m^2 (Pascals, Pa)

What is the atmospheric pressure?

100,000 Pa

What is the equation to calculate pressure in fluids (gas and/or liquids).

p = h x p x g (pressure = height/depth x density x gravitational field strength)

What is precision?

How close the measured values are to each other.

What is accuracy?

How close the measured values are to the true value.
