Presentation on theme: "Work Work is done only when a force moves an object."— Presentation transcript:
1 Work Work is done only when a force moves an object. When you push, lift, or throw an object, you are doing work.A force acting through a distance is work.
2 Work Work is not done every time a force is applied. A force can be applied on an object without work being done on the object. (wall example).
3 WorkAnother important requirement for work to be done is that the distance the object moves must be in the same direction as the force applied to the object. (groceries example)
4 WorkThe amount of work done in moving an object is equal to the force applied to the object times the distance through which the force is exerted:Unit of work is measured in joule (J).Work=Force x Distance
