Group 1

  • Object used for experiment: phone placed on the top of a spinning chair.
  • Acceleration vs. Time graph
  • Blue line ⇒ X-axis acceleration
  • Orange line ⇒ Y-axis acceleration
  • Grey line ⇒ Z-axis acceleration
  • Yellow line ⇒ overall acceleration

Group 1’s write-up:

With reference to the graph in the previous slide, the overall acceleration of a circular motion is roughly 10m/s^2. The vertical acceleration remained at about

0m/s2 , which makes sense as the phone did not move upwards or downwards during the spin, but only left to right and forward to backward. In other words, the phone only moved in a 2 dimensional space. Thus, there should be no vertical acceleration. The horizontal acceleration is about

-10m/s^2, which is equal in magnitude but opposite in direction to the overall acceleration. The Z-axis acceleration is about 3m/s^2.

Group 6

  • Circular Motion of spinning bicycle wheel
  • As the bicycle is being held off the ground as the wheel is spinning, the force exerted on the wheel to make it spin may shake the whole bicycle and cause inaccuracy of the wheel in circular motion.
