to calculatw the power produced by a force, the size of the force must be known. What else needs to be known to calculate the power

The other thing we need to calculate the power is the "Velocity".

A quantity of labor or work done to be accomplished within a particular period of timeframe is determined as power. It is denoted by "P".According to the given query, we are talking about the relation between Power and Force. Along with simple instances where such an item is moved at continuous speed by a constant force.

The relation can be shown as:

→

where,

P = PowerF = Forcev = Velocity

Thus the above is the right response.
