The quantities which can be measured by an instrument and by means of which we

can describe the laws of physics are called physical quantities. Till class X we have

studied many physical quantities

Read moreThese are the elementary quantities which covers the entire span of physics.

Any other quantities can be derived from these

Read morePhysical quantities which can be expressed in terms of basic quantities

Read moreBesides seven fundamental quantities two

supplementary quantities are also defined

Read moreConsider a term sin

Read moreIf the dimensions of the L.H.S and R.H.S are same, then we can say that this

eqn. is at least dimensionally correct. So this equation may be correct.

But if dimensions of L.H.S and R.H.S is not same then the equation is not

even dimensionally correct.

of force is
