Fundamental/Derived Quantities Flashcards
Measurements
What is a Quantity?
A quantity is anything that can be measured
Fundamental Quantities
What are the 5 fundamental quantities?
Specify symbol
Mass (m)
Length (l)
Time (t)
Temp (T)
Current (I)
Note: Current is the only expection & Temp is capital
Fundamental Quantities
What are the SI units for each fundamental quantity
Specify SI unit symbol
Mass - Kilograms (kg)
Length - Meters (m)
Time - Seconds (s)
Temp - Kelvin (K)
Current - Ampere (A)
mass is the only one whose SI unit is not a base (NOT GRAMS)
Measurements
What are phyical quantities a product of?
Numerical magnitude & unit
ie. 1.4 & meters
Derived Quantities
What are the 7 derived quantities?
Specify symbols
Area (A)
Volume (V)
Force (F)
Speed/Velocity (v)
Density (p)
Pressure (P)
Acceleration (a)
Density has a special character called a rho i just idk how to add it-
Derived Quanities
Defining Equations
A=1x1
V=1x1x1
F=ma (mxa)
v=d/t
p=m/v
P=F/A
a=v/t
