1. Apparatus comprising in combination:

  • (a) a net;

    (b) at least one sensor; and

    (c) at least one processor;

    wherein;

    (i) the net includes one or more components, each of which components comprises a material that has an electrical resistance that varies depending on the extent to which the material is stretched,(ii) the at least one sensor is configured to take measurements of changes in electrical resistance of each of the one or more components, respectively,(iii) the at least one processor is configured(A) to perform a computation to calculate, based at least in part on the measurements, a calculated value indicative of the translational kinetic energy of a ball that strikes or passes through the net, and(B) to output signals to cause an output device to render the calculated value in a human-readable form; and

    (iv) the calculated value is in a range, which range is the range of values that may be outputted by the computation, and which range includes more than two values.
