Curiously, rule 4.e forbids tests from asking participants to calculate dynamics. Preventing the calculation of force on objects seems to excise much of the physics behind such a physics event. Perhaps, though, I have misunderstood what this line is saying? My present understanding is that the rule disallows calculation of force for objects not in equilibrium, so students only need to grasp force conceptually. Is anybody able to clarify?

Basically, this rule only allows for calculations dealing with static equilibrium. This doesn't mean, however, that calculations involving motion are banned. If the objects in the system are moving at constant velocities and the net force/torque of the system is zero, then the calculation is allowed. In fact, most scenarios you can think of involving this event

*should* be allowed.

The only questions that

*wouldn't* be allowed (just off the top of the head) would be scenarios specifically dealing with acceleration or oscillating systems, in which case this event would become Hovercraft 2.0
