what is the significance of seconds squared [s^2]?

Question

Time moves at one constant. How can you have it raised to an exponent? If you have say: 3 seconds^2, is it actually 9 seconds?

In: 5

Answer 1

When you have s^2 as a unit, usually in a physics quantity, you do not square the number to get seconds. If a term is acceleration (m/s^2 ) then if you multiply by 5 seconds it cancels out one of the seconds in the denominator and gives you m/s = velocity.

These techniques, what’s sometimes called units analysis, allow you to have numbers with more meaning. Having a weight of 5g is more meaningful that just having a weight of 5.
