SUMMARY

The significance of 2π in the power formula, expressed as F × 2π × Revolutions, is that it accounts for the circular motion involved in the calculation of power. Specifically, 2π represents the total radians in one complete revolution, equating to approximately 6.28 radians. The formula integrates force and distance, where distance in circular motion is calculated as 2π multiplied by the number of revolutions. Additionally, the correct terminology emphasizes the distinction between distance and displacement, highlighting the equations for power as force times linear velocity or torque times angular velocity.

PREREQUISITES
  • Understanding of basic physics concepts, particularly power and motion.
  • Familiarity with circular motion and angular measurements.

The equation for power is:

F X 2pie X Revolutions

My question is, what is the 2pie for? I know that might seem obvious but I just can't see it.

thanks!

I haven't seen the derivation of the formula, nor ever heard of it before. However, since there are 'revolutions' mentioned, the 2pi would imply that mathematically, the power is dependent somewhat upon circles. Given C=2\pi r
 
I think I figured it out. 2pi = 6.28 radians, which is 1 complete revolution. So in the power formula you have Force X Displacement. To figure out displacement in a circle you take 2pi X the # of revolutions. I get it!
 
Yep that sounds about right. Just be weary about your terminology though. I believe the correct term would be distance rather than displacement in this case.
 
The equations for power are force times linear velocity, or torque times angular velocity.

The relationsips between angular and linear:

force = torque / radius
linear velocity = angular velocity x radius
