Work and Power

Purpose:
To develop the understanding of work and the properties of work. Then the new found concept of work will be compared and contrasted with the concept of power.

Equipment Used:

 The picture is of the stairs that the students will walk and run up. Next to the stairs over the railing there is a pulley system that has a backpack hanging over it and the students will raise it.
















Data Collected:
The data that was collected was the height of each step in a stair case and then the amount of steps in the stair case. This calculation gave the height, the delta y, that the force will be applied over.The force that is going to be applied will be the weight of the individual that is either walking or running up the stairs. The same concept is going to be applied to a pulley system with a weight at the bottom that is raised to the top. However the height of the stairs isn't going to be the distance that it will be raised will be different.

Calculations:
The force that is being applied over the height of the staircase gave work, however the time it took to accomplish that work was recorded as well. By dividing the work done by the time it took to do the work, then power is given.

Sincerely,
