Power is found by dividing work by what other physical quantity?Group of answer choicesdistancemassforcetime

To determine the correct answer to the question of what physical quantity power is divided by in the equation for power, let’s analyze the concept of power in physics.

Understanding Power

Power (P) is defined as the rate at which work (W) is done over time (t). The formula is given by:

$P = \frac{W}{t}$

Analysis of Options

1. Distance: This is not directly related to the calculation of power as it does not appear in the formula.
2. Mass: While mass is an important physical quantity, it does not play a direct role in the calculation of power.
3. Force: Force is related to work but not directly to the calculation of power.
4. Time: This is the key quantity we divide by in the equation, as power measures how much work is performed in a unit of time.

Conclusion

The correct physical quantity to divide work by in order to find power is time.

Final Answer

Power is found by dividing work by time.
