Work and Power Calculation in Physics

What is the formula to calculate power in Physics?

The data provided is related to the calculation of power. What formula should be used to determine power?

Answer:

Power is calculated using the formula:

Power = Work / Time

In Physics, power is a measure of the rate at which work is done or energy is transferred. It is the amount of energy that is converted or transferred per unit of time. The formula to calculate power is Power = Work / Time. In the data provided, it states that an engine does 400 J of work in 5 s. To calculate the power generated by the engine, we can use the formula above.

Given data:

Work = 400 J

Time = 5 s

Substitute the values into the formula:

Power = 400 J / 5 s = 80 W

Therefore, the power generated by the engine is 80 watts.
