The general thrust equation is then given by: F = (m dot * V)e - (m dot * V)0 + (pe - p0) * Ae. Normally, the magnitude of the pressure-area term is small relative to the m dot-V terms.

Witrynalets assume this meant they burned the same amount of calories/work/effort. so a motor with thrust of 5N for 5 seconds should in theory lift a rocket the same height as a motor that has 25N for 1 second. (5 * 5=25 * 1) they both do the same amount of calories/work/effort. other guys gave a better science explanation.
