a scalar

The mass of an object is

coordinates of B minus the coordinates of A

the position vector from A to B can be expressed by

A scalar equal to the product of the magnitude of the two vectors and the sin of the angle between them

The Dot product of two vectors produces

a third vector in the same plane as the other two vectors

Cross product of two vectors produces

50 degrees

If two directional angels of a vector are 50 and 50 degreees then the third directional angle is

square of the magnitude of vector F(F^2)

The dot product of vector F with the vector F is the

-30N-m

If the positon vector from the y axis to the force vector F= (10i+20j+30k) N is r= (1i+2j)m thent he magnitude of the moment of F about the yaxis is

the directional cosines of the vector

The constants in front of i,j,k of a unit vector are
