Calculating Work How do you calculate work? Work (W) is calculated by multiplying the the force, any push or pull, (F) applied to the object by the distance (d) the object traveled. Therefore the equation used to calculate work is (Work in joules)= (Force in Newtons) x (distance in meters) or W=F x d. By re-arranging the formula, you can also find missing numbers. To calculate force: F= W/d To calculate distance: d=W/F Eureka Video on Work:
Practice Questions: 1. After packing your backpack with textbooks and your binder before the weekend, it takes you 96 N to lift you backpack a distance of 1.5m. How much work have you already done before you have even started your homework?
2. Phineas got a parcel from the FedEx truck and found that it was his new flat screen t.v. He needs to lift his parcel up the stairs over a distance of 4 meters. If it takes Phineas a total of 1500N to lift the parcel, how much work has Phineas done to lift the parcel?
