SPH 4U – Collision Lab: Linear Air Track Purpose: To determine the unknown mass of a glider by approximating an elastic collision with a second glider of known mass on a linear air track. Hypothesis: Guess the mass of the unknown glider. Briefly provide your reasoning. Materials and apparatus: omit Procedure: Write your own procedure in past tense, passive voice. /5C Observations: Record only your observed values. (include the known mass) Sample calculations: Show the calculations required to solve for the unknown mass. /5T (Do not show multiple repetitions of the same calculation) Conclusion: Concisely state the value of the unknown mass. Please bold the value. /5A
