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 ...

It is seen that the contact force F is directly dependent on the Coriolis component of acceleration. Note that the sign on F changes as the sign on x_dot changes; that is, when the particle is moving ...
