What does universal efficiency mean?

What does energy efficiency mean? How does it relate to appliances in the home?

  • Answer:

    energy efficiency is best explained through this equation Efficiency = Work input / Work output x 100% you divide work output into work input because you will never get an efficiency of 100%. you will always lose energy through heat loss. that's why you multiply by 100 because you will always end up with a number less than 1. the kinetic energy of the first ball has decreased to 0 because it has stopped but its potential energy has increase.
