Question

Derived the s1 units of force,pressure and density?

Answer 1

Force: `f=(kgm)/s^2`
Pressure: `N/(m^2)`
Density: `d=(kg)/(m^3)`

Explanation:

Force is mass times acceleration, so:
`f=ma` `m` is mass in kilograms and `a` is acceleration in meters per second squared.
`f=(kg)(m)/(s^2)`
`f=(kgm)/s^2`

Pressure is measured in force over surface area, or `N/(m^2)`

Density is measured in units of mass over volume, so:
`d=m/V` `m` is mass in kilograms and `V` is volume in terms of meters cubed.
`d=(kg)/(m^3)`
