ACCELERATION:
The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.
FORCE:
kg*m/sec² This is an International system unit (SI unit) of for force. As this is derived by newton, This Force unit is also termed as Newtons. So, both kg*m/sec² and Newtons can be known as SI units of force. The same unit in CGS system is written as gm*cm/sec² or Dyne.
DENSITY:
The SI unit for density is: kilogram per cubic metre (kg/m3)
ENERGY:
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre.
PRESSURE:
The unit of Pressure is derived from the units of Force and Area, which are used to calculate Pressure. When using imperial units in the formula P = F/A, as an example, you'll see P = lb/in^2, which is abbreviated to psi. An example using common metric units, P = N/m^2, which is abbreviated to Pa (pascal).
