Kinematics in Two Dimensions
The position vector r of the point P. The unit vectors. The components x, y, z of the position vector r. The components Ax, Ay, Az of an arbitrary vector A. Vector A in two dimensions and its components. The vectors A and B and the angle between them. The component of A along B is A cos φ the component of B along A is B cos φ.
Description
Definition of Vector, geometric approach and algebraic approach are explained. Position vector, unit vector, component of vectors, addition of vectors, multiplication of vectors are all discussed. Suitable numerical examples in two and three dimension.s are solved.
