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.
