Question

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?

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

@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.
