Volume si units - Physics -meters cubed (m^3 (=1000L) )
Chemistry - Liters (L)
Si unit Force - Newton (N) which is kg·m / s^2 because it is mass times acceleration
Si unit time - Seconds (s)
Si unit Current - Ampere (Amp)
Si unit temperature - Kelvin (K)
Luminosity - Candella (Cd)
si unit for energy and work - Joules (J) which is N·m or kg·m^2/ s^2
Work formula - Force times displacement
W= xFcos theta
Kinetic.energy formua - KE= 1/2 mv^2
(think about the units kg· (m/s)^2. )
Potential energy - PE= mgh
So kg ·m/s^2 · m
Power formula - P= w/change in time (W)
, Watts - J/s or Nm/s or kg·m^2/s^3
Velocity formula - change in displacement/ change in time (m/s)
Acceleration formula - change in velocity/ change in time (m/s^2)
Definition of displacement - Vector- The difference from where you started to where you
ended in a straight line path (d, change in x/t, change in y/t)
Definition of distance - scalar- how far something moved in total
Force - F= ma
Density - italicized p = m/V (kg/m^3)
Pressure (Pascal) - P= F/Area Pa= N/m^2= kg/m x s^2
P= density of fluid x g x D Pa= (kg/m^3)(m/s^2)m = kg/m x s^2
