Experiment 1A: Friction - Question 1 Word limit: Min - 50 Max - 150 We want to test whether there is friction present on an air track. How would you go about testing this? Be descriptive and use equations where possible. Hint: What does friction do to a moving object?

Experiment 1A: Friction - Question 2 Word limit: Min - 50 Max - 150 After reading the experimental procedure, were there any similarities between this and your answer to Q1? Were there any aspects of your approach that you thought were better?

Experiment 1B: Question 1 Word limit: Min - 50 Max - 150 We would like to test whether totally inelastic collisions obey conservation of linear momentum and conservation of kinetic energy. How would you go about constructing an experiment to test this concept? Be descriptive and use equations where possible. Hint: What are the different types of collisions?

Experiment 1B: Question 2 Word limit: Min - 50 Max - 150 After reading the experimental procedure; were there any similarities between this and your answer to Q1? Were there any aspects of your approach that you thought were better?

Experiment 1C: Gravity - Question 1 Word limit: Min - 50 Max - 150 We want to experimentally determine Earth's gravitational acceleration. How would you go about this? Be descriptive and use equations where possible. Hint: How did Newton figure it out?

Experiment 1C: Gravity Question 2 Word limit: Min - 50 Max - 150 After reading the experimental procedure; were there any similarities between this and your answer to Q1? Were there any aspects of your approach that you thought were better? Please note that the equations in the worksheet assume that we have started the track from zero velocity (not the case in the video!). You can either start your cart from right near the first gate, or you can alter the equation to account for the initial velocity that it gains beforehand.
