Answer :
Work is force times distance and power is work over time, so you need to know force and distance to calculate both
A force is said to have done work, if it manages to cause a displacement in an object from its starting point. Power can be defined as the rate of doing work. The work can be calculated using the following formula:
Work done ⇒ Force × Displacement
The power can be calculated using the following formula:
Power ⇒ Work ÷ Time
In order to calculate the work and power, the force and distance should be known. The force and distance will help calculate the work, which will help in the calculation of the power of the object.
Hence, the answer is 'you must known force and distance to calculate both'.
