Question

Prove that power is the scaler product
of force and vocity .​

Answer 1

Answer:

The rate at which work is completed is referred to as power (or the rate at which energy is transformed or transferred). The scalar product of force and velocity is also power.

Explanation:

• In simple circumstances when a constant force moves an object at a constant velocity, the power is simply P = Fv.
• In a broader sense, if the velocity does not point in the same direction as the force, the scalar product of force and velocity must be employed.
• Despite the fact that force and velocity are both vector variables, power is a scalar number.
• It is not affected by the direction. It has just one magnitude since it is a 'amount' of effort that only has one magnitude.
