Motor Step Work

Repeated Steps Add Work

A repeated motor output keeps per-step work separate from total work. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Repeated motion starts from per-step work

Each checked step uses 12 joules of useful work.

Repeated steps add useful work

For 3 steps, useful work totals 36 joules.
