Power Lab

Purpose: To investigate what physical characteristics of students how it affect the power generated on running up the stairs.

Hypothesis: The student that can generate the highest power would probably be Adam K, because it is so obvious that he’s the most physically fit among every one of us. In addition, he’s muscular and sporty.

Variables and Controls:

        Independent Variable: the mass of all the students

        Dependent Variable: The force (Fg)

        Control: the vertical height of the stairs.

Materials:

        Meter Stick

Procedure:

        1. I made a table with columns name, Fg(N), Vertical Height (m), Work done, Power, Ranking

        2.  We measured the height of a one step, and then multiplied it to 14 since the stairs has 14 steps.        

        3. Then I used the stopwatch to measure how fast Xerxes made it to the top. Then record it on the time column of the table. Then Xerxes timed how long I took to reach the top.

        4. Then other partners did just like what we did, they timed each other.

        5. After that, we ...
