The Angle Between two vectors For angles
The Angle Between two vectors For angles Find the angle between
The Angle Between two vectors For angles Vectors are Orthogonal if there Dot Product (u●v)= 0 What is the angle between the vectors, Why?
Definition of Vector Components Let u and v be nonzero vectors. u = w1 + w2 and w1· w2 = 0 Also, w1 is a scalar of v The vector w1 is the projection of u onto v, So w1 = proj v u w 2 = u – w 1
Definition of Work Work is force times distance. If Force is a constant and not at an angle If Force is at an angle
