pt2.4 - testing of car

testing video:



1. using the data table from above, calculate the average velocity for your mousetrap car during the best run in the final assessment.

the best run was the first trial and the average velocity is 0.9m/s
3.53m/4.0s = 0.8825 = 0.9 (2 s.f.)

2. which part of your mousetrap car design worked best? explain your answer.

the wooden frame of our mousetrap car design worked best, as it was sturdy, hard, and held together the wheels and mousetrap firmly. even though we had some worries in the beginning that the balsa wood would not be able to support the heavy weight of the mousetrap, the frame turned out to be strong and steady enough to support the mousetrap and also to support the axles and wheels.

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

if given more time, we would make a few modifications to the mousetrap car. we would use a stronger material for the frame, such as carbon fibre rods or copper rods. we would also improve the wheels by using a stronger material such as wood and increasing the sizes of the wheels so that the car would be able to travel for a longer distance. and finally, we would increase the length of our lever so that our car would be able to travel for a longer distance.
