The purpose of this lab is to measure the amount of work and power generated in various
activities including stair running, high jumping, endurance jumping, and weightlifting.
The materials required for this lab are a meter stick, stop
1. Which activity required the most amount of work? Why?
The activity that required the most amount of work was Activity Three, the endurance
jump. In this activity, group members had 48-60 jumps within the thirty second time
span. Thus, the displacement
1. How can the amount of power generated for any activity be increased?
Increasing the amount of work increases the amount of power generated because power is
directly proportional to work done. Also, decreasing the time increases the amount of
Three poles were placed at three various sides of the lab table and pole clamps were
attached to each of the three poles to ensure stability. Then, spring scales were attached to each
pole. Pieces of string were attached to each spring scale.

How much glucose (C6H12O6) per liter should be used for an intravenous solution to
match the 7.65 atm at 37 C osmotic pressure of blood?
A hydrogen gas sample is collected over water. The volume of the sample was 190.0 mL
at 26C, and the pressure in

There are two kinds of momentum, linear and angular. A spinning object has angular
momentum; an object traveling with a velocity has linear momentum. For now, and
throughout chapter 7, we'll deal with linear momentum, and just refer to it as
