Explanation:

Power is defined as the rate at which work is done or energy is transferred. The formula for power is \( P=\frac{W}{t} \), where \( W \) is work (or energy) and \( t \) is time. The first option ("The number of joules over displacement") is incorrect because \( \frac{W}{d} \) (joules over displacement) is related to force (\( F = \frac{W}{d}\) from \( W = Fd\)). The second option ("The amount of energy it takes to convert and move an object over time") aligns with the power formula \( P=\frac{W}{t}\), as \( W \) represents the energy (or work) and \( t \) is the time.

Answer:

The amount of energy it takes to convert and move an object over time.
