Vector - correct answer A quantity that involves both magnitude and direction Scalar - correct answer A quantity that does not involve direction; Only has magnitude Magnitude of a Vector - correct answer |A| or ||A||=√((Ax)^2+(Ay)^2) Angle or Direction of a vector - correct answer θ=tan⁻¹(Ay/Ax) Dot product - correct answer The multiplication of two vectors which results in a scalar. A·B=|A||B|cosθ=AxBx+AyBy Cross product - correct answer The multiplication of two vectors ...

1. We can choose δx = 0, δy = δ. The equation of the ellipse x = cosθ cosωt y = sinθ cos(ωt − δ) reads in Cartesian coordinates The direction of the axes is obtained by looking for the eigenvectors of the matrix which make angles α and α + π/2 with the x-axis, where α is given by tanα = cosδ tan2θ The vector product of the position ~r with the velocity ~v, ~r ×~v, is easily seen to be so that the sense of rotation is given by the sign of the product sin2θsinδ...

Scalars correct answersQuantities that are fully described by a magnitude alone. Vectors correct answersQuantities that are fully described by both a magnitude and a direction. Distance correct answersScalar quantity that refers to "how much ground an object has covered" during its motion. Displacement correct answersVector quantity that refers to "how far out of place an object is" it is the object's overall change in position. Speed correct answersScalar quantity that refers t...
