Is Power the Same as Energy? A Biomechanics Question

AI Thread Summary
Power and energy are distinct concepts in biomechanics, with power defined as the rate at which work is done over time. Power can be expressed as mass multiplied by acceleration and speed, while energy relates to the capacity to perform work. The confusion arises from the relationship between force, mass, and acceleration, where force equals mass times acceleration. Einstein's equation, E = mc², pertains to energy but does not equate power with energy. Clarifying these definitions is essential for understanding their roles in biomechanics.

Hey today in class the subject was biomecanics.

My teacher wais that

Power = Masse * accelleration

This puzzles me becuase 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

Somebody is off.

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

And power is not the same thing as energy anyway.
 
If anything, power=mass*acceleration*speed.

\begin{align}<br /> power &amp;= \frac {work} {time}\\<br /> &amp;= \frac {force \times displacement}{time}\\<br /> &amp;= mass \times acceleration \frac {displacement}{time}\\<br /> &amp;= {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)
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds?

Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
