Why we use constant in physics formulas.kindly expl?
Answers
Answer:
The main reason we have to put constants in formula of physics is units.
See, all the units, even the SI units () have been defined by us humans arbitrarily.
For eg.- A second is defined as 9192631770 periods of radiation(light) emitted by transition of electron between two particularly defined levels of the caesium-133 atom. See it is arbitrary definition. You could ask that why is it not 9.2 billion periods or 9192632885 periods. Similarly other fundamental or base units() have also been defined arbitrarily.
But the universe does not have to comply to our system of units and make constants in every formula as 1. Rather the universe has already defined relations between quantities and what numbers we should get when solving them and it is us who have to make the formulas or equations satisfy the truth according to our units. That’s why we add constants in
Answer:
We need it just because of the way our unit of force, the newton, is defined: 1 newton is defined as the force needed to give a mass of 1 kilogram an acceleration of 1 meter per second squared. ... We need the physical constants to convert the effects of nature into the units of our choice...
