Explanation:

3. Have each member of your lab group remove one shoe. Use a spring scale to determine the magnitude of maximum static friction for each shoe on two different surfaces. (Depending on the sensitivity of the spring scale, you may need to load the shoe with weight.) Present your results in a table and write a paragraph explaining the results.

Explanation:

4. Drop five different balls from a height of 2 m on two different surfaces and carefully observe and record the bounce heights. Calculate the coefficient of restitution for each ball on each surface and write a paragraph explaining your results.

5. Using a stopwatch, time each member of your lab group running up a flight of stairs. Use a ruler to measure the height of one stair, then multiply by the number of stairs to calculate the total change in height. Calculate work, power, and change in potential energy for each group member.
