11/10/2010 Name: Sharan Multani Name: Nick Podreborac M7 - Conceptual Questions Q1.) A torque is a product of a force and a distance (lever arm). Work is also the product of a force and a distance. Yet, “torque” and “work” different. What is it about the distances that make “torque” and “work” different? Ans1.) Torque is the cross product of the force and the distance, giving a measure of the rotational force acting on an object. There is not necessarily any movement in torque. Work is force multiplied by distance giving you the energy expended on an object. Even though the formulas are similar, the principles are different. Consider trying to turn a bolt using a wrench. It may or may not turn, depending on how much resistance there is and how much force you apply to the wrench. If the wrench does not move, there is no work done (your force is applied but there is no movement as a result). If you know about vectors this will explain it.
