We discussed energy and elicited that we only observe the effects of energy and not the energy itself, and when it is transferred from one place to another or from one force to another. Recalling that impulse is a change in motion (and momentum) and is related to a force and how long the force acts, the formula for impulse was again stated as force x time. After questioning, the term "how long" was found to not only mean time but may also refer to distance. We then can have force x distance, which is defined as the property called work. Work = force(net) x distance. Demonstrations of lifting a given weight, in Newton's, a distance of 0.1 meters above the desk and then determining the work done, and comparing it to lifting the same weight 0.2m and comparing its work done showed twice as much work done. The unit of work is NxM or Joules. Solving a few problems to determine the work done moving a force over a given distance was utilized. It was stressed that once the mass was lifted, and held in place, no work was being done on it.
