Group 1:

Circular motion of a spinning chair.

  • The experiment was conducted over 30 seconds, with the phone attached to the top of a spinning chair, rotating at varying speeds.
  • Additional cloth was placed in between to ensure that the phone would not slip during rotation.
  • The experiment was repeated multiple times and similar results were recorded.

​

Conclusion:

  • From the graph, it can be concluded that centripetal acceleration increases at an increasing rate as the angular velocity increases.

Group 4

  • A fan spins in a circle, and this creates circular motion for an object fixed to the wing of the fan
  • Hence when the fan starts to spin, the speed of the phone is constant. However, the direction of motion is not constant, it changes. The velocity is not constant.
  • Hence the acceleration (rate of change of velocity) of the phone is increasing at a constant rate.

Group 6 - Reflection

Experiment�Circular Motion of a Handheld Toy Fan

Procedure�We decided to attach a mobile phone to a handheld toy fan using bluetack

When the play button is pressed on the phone, the fan is rotated using the handle for 20s, causing the phone to rotate in a circular motion as well

Results

Over 20s, the linear acceleration x and y of the toy fan decreases

A negatively charged particle moves in the plane of the paper in a region where the magnetic field is perpendicular to the paper. The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.
