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 ...

Forces arise between objects, the forces on these objects are equal and opposite. Friction is a force that always opposes motion. Force is measured in newtons (N).

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 ...
