Question

what is dot product​

Answer 1

Answer:

the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number. ... Geometrically, it is the product of the Euclidean magnitudes of the two vectors and the cosine of the angle between them.

Answer 2

$\huge\underline\mathfrak\red{answer}$

In physics, vector magnitude is a scalar in the physical sense, i.e. a physical quantity independent of the coordinate system, expressed as the product of a numerical value and a physical unit, not just a number. The dot product is also a scalar in this sense, given by the formula, independent of the coordinate system. Examples include:

Mechanical work is the dot product of force and displacement vectors,

Power is the dot product of force and velocity.
