Relationship between force and workWork is simply
the application of a force over a distance. The distance only counts if it is in
the direction of the force you apply. Lifting a mass from the ground and
putting it on a shelf is a good example of work. The force is equal to the
weight of the object, and the distance is equal to the height of the shelf. Work done is
defined as the product of the force and the distance over which the force is applied:
Work done = Force x distance or W = F x d. Work is measured in newton-metres
(Nm). It is a unit also known as the joule (J). Force
is measured in newtons. Distance is measured in metres. You are going to
calculate the work you do to lift some masses.
This show how the Force and the Distance sensors were set up to study work. View and/or download the worksheet View and/or download the Datadisc file examples of this investigation
