Plot a graph of resultant force F in N on the y-axis against acceleration a in m/s 2 on the x-axis. Draw the line of best fit. The graph is a straight line through the origin. This tells us that ...

I can measure the magnitude of the force from the fan by turning it on and letting it push up against a force probe. With this, it seems to push with a force of about 0.2 Newtons (your fan may vary).

The disk is rotating at a constant rate, Ω. We desire to understand the reaction force of the disk slot on the particle as the particle moves back and forth within the slot. For the analysis, we will ...
