The article would be easier to read if the type was darker.
 
Fix typo: "pendulum started" instead of "pendulum stated" ?

Thank you, there must be "pendulum is placed" ,i do not know how to fix it
 
it is very interesting, but its value is negative, because it does not state the problem to solve, meaning what are servo constraints? what "problem" did it solved (back in 1922)?
or maybe this is an article directed to whom ever knows the THING and not layman, if so...apologies.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
