These other definitions often serve to confuse students. It is this definition that will be used here. Work is the means by which energy is changed from one form to another. When work is done on an object, therefore, the object is said to have either gained or lost a certain amount of energy of a particular type. Work is considered to be positive, negative, or zero in value, depending on the direction of transfer.
Work is accomplished on an object any time a net force acts over a particular displacement , d .
Computer programs that perform integration calculations do so using various numerical techniques. Science Workshop has the ability to estimate the area under a particular plot of data using one of these methods. The Work-Kinetic Energy Theorem describes what happens when the Net Force does work to cause the kinetic energy of the object to change. Therefore, it will be more efficient to take the time to completely set up Science Workshop before starting the lab activities. Place the motion detector at the end of the 1.2 meter track.
