please help write a hypothesis for my lab report please
Observation: Height of Stairs(m) 2.68 My Mass(kg) 52 Time Walking(s) 8.09 Time Running(s) 4.63 Analysis: 1. Determine the work done against gravity to lift your mass up the stairs 2. Determine the power you developed while walking up the stairs 3. Determine the power you developed while running up the stairs 1. Wnet = APE = final PE - original PE Original PE = mgh = 52* 9.818*0 = 0 Final PE = mgh = 52*9.81*2.68 = 1,367.1216 Wnet = 1,367.1216 2. P = W/T Work = 1,367.1216 Time = 8.09 1,367.1216/8.09 = 168.989 The power gained from walking up the stairs is 168.989 3. P = W/T Work = 1,367.1216 Time = 4.63 1,367.1216/4.63 = 295.27 The power gained from running up the stairs is 295.27Title: Human power: Climbing stairs Purpose: The purpose of this lab is to determine the work done and power developed while climbing a ight of stairs Material: 1. Stopwatch 2. Bathroom scale 3. Metre stick or measuring tape '1 . Use the metre stick or measuring tape to measure the vertical height of a ight of stairs, as indicated in the following diagram. Record this value in the observations table. You can do this at home, or you can use stairs at a school, or other public building. Measure this vertical height 2. Use the bathroom scale to nd your mass in kg. Record this value in the observations table. If your scale measures in pounds. convert to kilograms by multiplying the number of pounds by 0.45 to get the number of kg. 3. Time how long it takes you to walk up the ight of stairs (in seconds). Record this value in the observations table. 4. Time how long it takes you to jog or run up the ight of stairs {in seconds}. (Always take a great deal of care when running on stairs!) Record this value in the observations. Discussion/Conclusion: From conducting this experiment, it becomes evident that the work performed while ascending the same set of stairs remains consistent regardless of the amount of power exerted. Furthermore, I deduced that a shorter duration for ascending the stairs correlates with higher power output. Therefore, to optimize power generation during stair climbing, it is essential to ascend the stairs as rapidly as possibleStep by Step Solution
