Work and Power

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.
