PT3.2 - Post-testing dicussion

Using your data from 3.1, calculate the average velocity of your mousetrap car during the best run in the final assessment.

7.5 / 7.19 = 1.04m/s (3sf)

Which part of your mousetrap car worked best? Explain your answer

The release mechanism worked well as the sand paper had enough friction for the rope to hook on but not too much so that we can let the car travel on its momentum when the string came loose. The custom made tyres were very smooth which allow the gluing of rubber bands on it to increase the traction in had with the ground. Another point lies in the ball bearings connecting the axle to the chassis. We oiled it a lot to reduce the friction of a very minimal friction design.

If you had more time to work on your mousetrap, state and explain how you will improve/modify the current design?


We would strengthen the design and rebuild the hood that was unfortunately destroyed. Also, we could have glues rubber band to the front of the wheels
