Question

Introduction: To complete this activity, a stairway was used in the main hallway and was measured with a meterstick. The height of the staircase is 4.84 meters. The student was asked to step on a bathroom scale to measure their weight in pounds. Scale weight = 104.89 lbs. (2.2 lbs = 1 kg). Then during the day, times were noted for having to walk, trot, and run up the staircase. Walking time; 14.99 sec, trotting time; 9.85 sec, running time; 6.40 sec.

Purpose: This activity is used to develop the concepts of work, energy, and power as a student was measured for work, potential energy, their power level, and the speed in which they climbed a staircase during a typical school day.

Answer 1

This activity involves measuring work, energy, and power while climbing a staircase. By calculating the work done in climbing the staircase and dividing it by the time, the student can determine their power level. The speed at which they climb the staircase can also be determined.

Step-by-step explanation:

In this activity, the student is measuring work, energy, and power while climbing a staircase. The height of the staircase is 4.84 meters. The student measures the time it takes to walk, trot, and run up the staircase, and also measures their weight using a bathroom scale. By calculating the work done in climbing the staircase and dividing it by the time, the student can determine their power level. The speed at which they climb the staircase can also be determined by dividing the height of the staircase by the time it takes to climb it.
