It clarifies that energy can be changed in form but is not destroyed or created, and introduces the work formula W=Fd to quantify energy at work.

happen.There are twotypes of energy:potentialand kinetic.Potential energyis stored energy—it is notbeing used.Kinetic energy isenergy in motion or at work.  \nDid you just lift this book?You needed energy to doit.Did water flow from thefaucet when you brushedyour teeth this morning?Energy did that,too.Didyou turn on a light today?Did you ride in a car,bus,ortrain?Are molecules flyingaround in the air?All thesethings happen because ofenergy.In fact,all day,everyday,energy is on the movein you,around you,andthroughout the universe.  \nEnergy comes in a varietyof forms.When youfip a switch and a lightcomes on,that’s electricalenergy.When the lawnmower cuts the grass,that's mechanical energy.Everything—includingpeople—uses energy.  \nWhat is energy?Energy hasbeen defined as the abilityto do work.That means that  \nBut even though energy isbeing used every second,it doesn't get used up.Itcannot be destroyed,andit cannot be created.Thetotal amount of energyin the universe doesn'tchange.It can be changedinto various forms,but thetotal quantity ofenergy isalways the same.  \n# Hou Much Energu?\n\nScientists use a formula to showenergy at work.They say thatwork(W)is the force exerted(F),multiplied by the distance(d).The formula is W=Fd.This makessense.Pushing an object anydistance takes energy.And it takesmore energy to push a
