Analysis: (each student does their OWN analysis) 1) What name is given to the rate at which work is done? What are the units of this rate? 2) In which activity did you have the most power? Which muscle group did you use? Running UP the stairs. You used most of your body like your arms, legs, calves and much more. 3) Explain how a large force can still end up with a small amount of power. (Hint: 2 ways) If the time to move + the force, takes longer, the power will be less. 4) Why might the power for two activities using the same muscle group (running up the stairs & jumping, or arm curls and push-ups) yield different amounts of power? (Hint: 3 ways...think about the variables in your equations when answering this.) Arm Curls had less force than Push UPS, but arm curly had a bigger displacement which means 5) Suppose you ran up 2 flights of stairs instead of just 1, to where you double the distance. By what factor does the work done change?A single repetition (rep) is doing the activity once. Therefore, you will have 1 rep when going up the stairs, and you will have 50 reps if you do the arm curls. Special Notes: * Arm curls: you are lifting the mass a certain vertical displacement, measure this carefully * Jumping: try to keep your jump a consistent height * Push ups: you are not lifting your entire weight, it is approximately 2/3 your total weight * Run up stairs: no running starts! Just run up a single flight, don't go around the corner * Show all of your work in the boxes in the data table.
