Question

define dimensions of a physical quantity​

Answer 1

Answer:

We will take an example of force

Explanation:

to find dimensions of physical quantity

we need fundamental quantities like Length Mass Time

first we will write formula of acceleration

F=m×a

F= M rest to 1

resonance in mass 1 M is present therfore F= m × a

now in acceleration =velocity ÷time

the to calculate the dimensions of velocity we need=disp÷time

disp means length MEANS L and there are Time2 in numerator in the formula of velocity and acceleration when T go in denominator it became T rest to-2

Let us write dimensions of force

F=M rest to one and L rest to 1 and T rest to -2

from above conditions
