Analîza Dimensiyonel - Pirsgirêk û Çareseriyên
1. Li gorî analîza boyûzan, boyûzên fîzîkî yên jêrîn ên ku xwedî boyûzên wekhev in diyar bikin.
B. hêz û zext
C. Hêz û momentûm
D. kar û germî
Tê zanîn:
Dimension of length = dimension of width = dimension of displacement = L
Dimension of time = T
Dimension of mass = M
Areserî:
Dimension of area = pîvana dirêjahiya x dimension of width = [L][L] = [L]2
Dimension of velocity = dimension of veguhestinê / dimension of time = [L] / [T] = [L][T]-1
Dimension of acceleration = dimension of velocity / dimension of time = [L][T]-1 / [T] = [L][T]-1[T]-1 = [L][T]-2
Dimension of force = dimension of mass x dimension of acceleration = [M][L][T]-2
Dimension of work = dimension of force x dimension of displacement = [M][L][T]-2 [L] = [M][L]2[T]-2
Dimension of power = dimension of work / dimension of time = [M][L]2[T]-2 / [T] = [M][L]2[T]-2[T]-1 = [M][L]2[T]-3
Dimension of çap = dimension of force / dimension of area = [M][L][T]-2 / [L]2 = [M][L][T]-2 [L]-2 = [M] [L]-1[T]-2
Ebat of momentum = dimension of mass x dimension of velocity = [M][L][T]-1
Dimension of heat = dimension of energy = dimension of work = [M][L]2[T]-2

Nîşe:
Germa is energy that moves due to the temperature difference.
Work is the process of energy transfer through the displacement of objects.
So, the dimension of heat = the dimension of energy = the dimension of work.
2. Two quantities that have the same quantity but have a different physical concept…
A. Force and momentum
B. Energy and force
C. Potential energy and kinetic energy
D. Energy and momentum
Areserî:
Unit of potential energy = unit of enerjiya kînetîk = unit of energy = unit of work.
Although it has the same unit, but the potential energy and the kinetic energy are different types of energy.

3. The following quantities that have the same units are…
A. Force and emf
B. Lezbûn û lezbûn
C. Kar û enerjî
D. Work and power
Areserî:
Work is the process of energy transfer through the displacement of objects.
Energy is the ability to do work.
Work and energy are two quantities of physics that have the same unit.
