11W (15N) (10m) = * W = 150 Let Practice! W = F * d N * m Joule (J) Rita mows lawns on the weekends. If she uses 15 N of force to move a lawn mower a distance of 10 meters, how much work does Rita do?W = F * dW(15N)(10m)=*W = 150N * morJoule (J)What are the units?
12So what’s this energy buinsess and how does work fit in? Energy- is the ability to do workPotentialKinetic
13Potential EnergyThe energy an object has by virtue of its position in a gravitational field.The higher an object above the ground the more potential energy.
