Momentum /collision lab. Since there was no lab sheet provided, you must write a complete report with all sections as described in the course guide.
Stair climb lab. Most of the work was due to changing PE, which depended on the change in height x m x g. The change in height was 4.27 m. The work associated with changing PE did not depend on the time but only the mass x g. The power then depended on work divided by time and thus increased with decreasing time to do the climb. However, you were asked to find the additional work and power associated with the kinetic energy needed. The KE did depend on the time. Also it depended on the total, not just vertical, distance. We approximated this as 10.04 m. While the KE was negligible for the slow cases, it was marginally significant for the fast cases and this should have been calculated and discussed.
Ballistic pendulum. ( Sect 4 hasn't done it yet) Lab reports should discuss why the equations used are valid and when and why momentum was conserved and energy wasn't ( inelastic collision between ball and catcher) and when energy was conserved and momentum wasn't (pendulum travel after collision).
