Power is described as the Velocity at which Force is applied to an object (P=F*d/t)
However, how are the Force and Velocity independent? Doesn't the Force applied affect the Velocity of the object?
For example, let's say you want to lift a 19.62N (2kg*9.81m/s^2) object upwards 1 meter in 1 second. The way I see the problem solved online is that you would need 19.62W = (19.62N*1m/s). However, with this applied Force the object is in equilibrium (and not moving or moving at an arbitrary constant velocity), so the work and power would be zero.
I must have something wrong here. Thanks.
