Student Instructions for Wednesday, March 8th

Hopefully you wore comfy shoes today.  You'll be collecting data in one of the stairwells at West High.  Use the measuring tapes to figure out the delta Y between the ground floor, and the top floor.  We'll be looking at how quickly you convert your Ee?Eg?Eth?Ech?Eo? into Eg, assuming you arrive at the top step with a velocity of more or less zero (no Ek at the top).  Power is the time rate of change of Energy Transfer, Delta Energy over Delta Time.  The units are therefore N*m/s or J/s which is commonly referred to as Watts.  746 Watts are equivalent to 1 Horsepower.  Once you've collected your data for walking safely up the stairs, and running briskly, yet safely, up the stairs, record your Hp value on this chart, and we'll see who is the Most Powerful Trojan!
