In biomechanics, power is defined as the product of which two factors?

Explanation:
Power is the rate at which work is done. Work is force applied through a distance, and power is work per unit time, which simplifies to force multiplied by velocity (how fast that distance is covered). In biomechanics, force corresponds to strength and velocity corresponds to speed, so multiplying these two gives power. The other options don’t capture the idea of rate: distance and time give speed but not the rate of doing work, force with displacement gives work, and mass/height relate to inertia or potential energy rather than the instantaneous rate of work.
