3. The SI System of Units a.k.a. “The Metric System” a.k.a. MKSA
M for meter, K for kilogram;S for second, A for ampere.
Other units(e.g. Joule,Newton) are derived from these.
“Always stick with SI units and everything will come out ok.”

4. Specific Units Length: meter(m); Time: second(s); Mass: kilogram(kg).
Length(m); speed(m/s); acceleration (m/s2)
units: Kg m/s2=Newton(N)
Energy: N m=Joule=Kg m2/s2=J
Power: energy/time=J/s
