Work and Power

Published on 07/08/2010

Activity Overview

Students explore the relationship between power, work, and time. They also explore the relationship between power, force, and speed. Based on these explorations, students derive the equation P = Fv and solve problems dealing with power in various mechanical problems.

Key Steps

  • Image

    Students should open the TNS file and read the first three pages. Page 1.4 shows a simulation of a block on an inclined plane, together with a graph of force vs. displacement.

    Next, students should calculate power for the simulation on page 1.4. First, students should use the Text tool (Menu > Actions > Text) to place a text box somewhere on page 1.4.
