The Lab Handout: Lab-ConservationOfMomentum.doc
This is how I graded the Momentum Lab, and in the little videos I work out that data from a set of data using the range finder.
5 pts - (DT) A neat data table with units and uncertainties for all the quantities you used to calculate the momentum before and after
5 pts - (p=?) Your calculations of the momentum before and after the gliders collide
5 pts - (Dp) Your calculations of the uncertainty of the momentum before and after the collision
5 pts - (CD) You citing the momenta before and after, and their uncertainties to build a case as to whether the data supports conservation of momentum or not.
5 pts - (E) Discuss 2-5 sources of error
5 pts - (I) For each of the above suggest an improvement to minimize the error from that source
