I'll medal anyone I just don't understand this lol What are the three measurements you need to make in order to calculate power? What are the units of those measurements?

    I'm not sure what they mean by 3 measurements. There are different ways to calculate power. \[Power = \frac{Work}{time}=Force \times Velocity \] Power is measured in Watts (W). Time could be measured in seconds, minutes, etc. Work is measured in joules (J) because it is a form of energy. Force is either measured in Newtons (N) or pound (lb). Velocity can be measured in any unit of distance per unit of time. Ex: m/s, or ft/min. Knowing this, we can also say that Power is measured in J/s (if we use seconds for time) or N*m/s.

    could be power where some measurements could be taken are things like resistance, current and voltage?

    but even then you only really need two to find power...

    @zephyr141 I think N*m/s is similar to what she's looking for. It says 3 measurements, which in this case would be measurements of force, distance, and time. That's just my guess though.
