What is the sum of multiple vectors known as?

A. Cross Product


B. Moment


C. Resultant


D. Scalar

What is the sum of multiple vectors known as?
Its C. Resultant





cross product has something to do with multiplication .. not addition





moment is the product of the force with its perpendicular distance from origin.





resultant is the result of 2 or more vectors which is found by adding them





scalar is a non-vector number (doesnt hv direction)
Reply:it's resultant





if you want to know an easy way to figure this out in future, go to google, and type:





define:resultant





or whatever terms you have until you come up with the right one. Instead of giving you lots of extraneous data, it just gives you straight-out definitions.
Reply:it is D scalar know can you answer my question
Reply:It is the resultant





Cross product is to multiply the vectors, to find a vector that is perpendicular to the initial vectors. (You'll have to imagine your world in at least 3 dimentions then, since in 3 dimentions you only have x,y and z coordinates)





"Moment is a quantity that represents the magnitude of force applied to a rotational system at a distance from the axis of rotation." Associated with rotational kinematics.


see http://www.wikipedia.org





A scalar is a non-vectorial measurement.
