Physical World and its Measurements(Part-3)
Dimensions
The Dimensions of a physical quantity to which the units of base quantity are raised to represent a Drive Unit of a quantity.
Some physical quantities with there dimensional equations:
1)Area- Length x breath
=L x L=L2
=[M0L2T0]
2)Volume- Length x breath x height
=L x L x L =L3
=[M0L3T0]
3)Velocity-Displacement
Time
=m =L =LT-1 =[M0L1T-1]
s T
4)Acceleration- Velocity
Time
= Distance =m = L =LT-2 =[M0L1T-2]
Time x Time s2 T2
5)Force-Mass x Acceleration
Mass x Velocity
Time
Mass x Distance
Time xTime
Mass x M = m x L = m x LT-2 = [M1L1T-2]
T2 T2
