Derive the formula of equations using dimensional analysis by Kisembo Academy.

dimensional analysis is analysis using the fact that physical quantities added to or equated with each other must be expressed in terms of the same fundamental quantities (such as mass, length, or time) for inferences to be made about the relations between them.
here we use dimensional analysis as a technique to derive equations or call it to find formula of a quantity using dimensional analysis. This is only possible when we have an idea about the factors upon which a physical quantity depends. here we explore fundamental and physical quantities of matter. The three basic quantities of matter include length, mass and time, their standard units being meters, kilograms and seconds respectively. All the physical quantities (derived quantities) are related to these three basic quantities. The basic quantities cannot be expressed in terms of other physical quantities whereas the derived quantities are physical quantities which are expressed in terms of other physical quantities and they include but aren’t limited to velocity, acceleration, force etc.

Isn't z supposed to be 1/2? Because the dimensions of period T is T to the power -1?? Not 1.. please correct me if am getting it all wrong.
@KisemboPhysicsAndMath
@KisemboPhysicsAndMath 4 года назад
-2z = 1 So divide both sides by {-2} sothat we get rid of the - 2 to remain with z alone. -2z/-2 = 1/-2 On the left hand side, - 2 cancels out with - 2 to give you z. On the right hand side, 1/-2 gives -1/2 { remember when you divide a positive by a negative, you get a negative answer} Hence Z = - 1/2. Let me know if it's still confusing sothat I find another way of explaining it...
@mariotito3024
@mariotito3024 4 года назад
To come up with the equations we collect the powers of the dimensions on both sides right? Like on the RHS MASS is to the power y and on the LHS it is 0 because we don't have MASS on the LHS...and that is why it is y=0. Now for TIME on the RHS we have -2z, and on the LHS we have -1 Meaning -2z=-1.. because the dimension of period is -1 and not 1.
@KisemboPhysicsAndMath
@KisemboPhysicsAndMath 4 года назад
Watch the video closely.... For TIME, we have T raised to the power 1 on the LHS and NOT -1
@KisemboPhysicsAndMath
@KisemboPhysicsAndMath 4 года назад
According to the question, T on the LHS is raised to the power 1 NOT -1

Please in the case of 1=-2z. you said the answer is equals to -1/2 but isn't it meant to be 1/2 if it isn't, please explain how
@KisemboPhysicsAndMath
@KisemboPhysicsAndMath 5 лет назад
Ooh, the answer is meant to be - 1/2. Lemme do it here step by step... -2z = 1 So divide both sides by {-2} sothat we get rid of the - 2 to remain with z alone. -2z/-2 = 1/-2 On the left hand side, - 2 cancels out with - 2 to give you z.
