How to calculate the power

1 answer

Power can be calculated using the following formula:

Power = Work / Time

or

Power = Force x Distance / Time

Where:

Work is the amount of energy transferred when an object is moved over a distance by a force.

Time is the duration over which the work is performed.

Force is the amount of energy required to move an object over a distance.

Distance is the length of the path over which the force is applied.

For example, if a person lifts a 10 kg weight to a height of 2 meters in 5 seconds, the power can be calculated as follows:

Work = mgh = 10 x 9.8 x 2 = 196 Joules

Time = 5 seconds

Power = Work / Time = 196 / 5 = 39.2 Watts

Therefore, the power required to lift the weight is 39.2 Watts.
