Is Power the Same as Energy? A Biomechanics Question

[XshulderX]

Hey today in class the subject was biomecanics.

My teacher wais that

Power = Masse * accelleration

This puzzles me because why is power not = energy?

I my World it can't be the same because Einstein said:

E = M * C²

Is power ≠ Energy or should my teachers definertion of power be changes to Power = Masse * accelleration²

 

[SteamKing]

Somebody is off.

Force = mass * acceleration. (F = ma, one of Newton's Laws)

And power is not the same thing as energy anyway.

 

[Borek]

If anything, power=mass*acceleration*speed.

$$\begin{align}<br /> power &= \frac {work} {time}\\<br /> &= \frac {force \times displacement}{time}\\<br /> &= mass \times acceleration \frac {displacement}{time}\\<br /> &= {mass \times acceleration \times speed}<br /> \end{align}$$

(not that it makes much sense in terms of solving any particular problem, but at least units are OK)
