Units of Power - in M, L, and T please

corglass · 2007-10-10 15:58:35

Quick question. Can someone please help me on this. I'm looking for the Units of Power (W) in terms of Mass (m) Length (L) and Time (T). Even point me in the right direction. I've only got to Power = energy / time Thanks Corglass

Ah, dimensional analysis

OK, you're right so far

Power = Energy / Time

Energy has the dimensions of [Mass] * [Length]^2 /[Time]^2 (Take the formula for potential energy and convince yourself of this)

So Power is [Mass] * [Length]^2 / [Time]^3
