I am not sure what exactly you mean by "reactive power" (I guess you mean electrical reactive power), but power is the ratio of energy for a period of time. So that makes power (and reactive power as well) a scalar, since you can describe it with only one number. The fact that electrical reactive power is drawn on a XY plane, should not confuse you.
The plane in which the reactive gyroscipic couple acts is called the gyroscopic plane
Like, Power Redundancy?
Yes there are. There are sliding gears inside power drills.
horse power
The capability maturity model focus on process improvement, measured and controlled, characterized for the organization and is proactive, and projects. This project is often reactive, unpredictable, and this also used for appraisal program and administrative services.
Well it is technically a vector because it has a magnitude and a direction on zero degrees. Reactive power will have a direction of either + or - 90 degrees and apparent power will be the vector sum of the real and reactive power.
vector
Power can be scalar or vector, e.g d/dt torque = vector power; d/dt mcV = mcA a vector power.
Power should be only scalar as there is no direction to the power, just the magnitude.
scalar lol
vector, power= work/time and work= force * distance, force is vector.
A scalar times a vector is a vector.
vector
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
current is vector or scalar
Power is the time derivative of energy, E. Energy can be scalar or vector. Thus power can be scalar or vector. Energy is a quaternion and consists of a scalar or real part Er and a vector part Ev. Energy E=Er + Ev, for example E= FR = -F.R + FxR = -FRCos(x) + FRsin(x). The real part is a scalar called "Energy" and the vector part is called "Torque" but has the same units Joules. Energy is defined by the units. P=dE/dt = d(Er + Ev)/dt = dEr/dt + dEv/dt = Pr + Pv. Power can be a scalar or a vector or both.
scalar direction is a vector quantity
