Hi all!
I came across 2 questions on my course work, and i don't know what is required here, can some one help please?
Q.1 Define the common derived units of the following physical quantities; and express them in terms of the base units: Mass, Length, Time and Electric charge (or Electric current);
Force, Velocity, Acceleration, Energy, Density, Pressure, Power, Momentum, Speed
Q.2 Define the common derived units of the following physical quantities:
P = mv - P = Kg.L/T
EK = ½ mv2 - EK = ½.Kg.(m/s)2
Ep = mgh - Ep = Kg.m/s2.m/s.s
v2 = u2 + 2as. - (m/s)2 = (m/s)2+2.m/s2.m/s.s
S = ut + ½ at2 - m/s.s = m/s.s.s+½.m/s2.s2
P = w/t - P = Kg.m/s2.s
F = ma - F = Kg.m/s2
t = t’/√(1 – (v2/c2)) no idea
Thank you for your help
