2.2 Vectors

Those physical quantities which require magnitude as well as direction for their complete specification are known as vectors.

Examples:

Displacement: The change in position of an object. It has length, a distance (magnitude) and a direction (e.g., $10\,\mathrm{m}$ towards west).

Velocity: The speed of an object in a particular direction (e.g., $50\,\mathrm{km\,h^{-1}}$ towards west).

Acceleration: The rate of change of velocity that occurs in either speed or direction or both (e.g., $10\,\mathrm{m\,s^{-2}}$ upward).

Force: A push or pull acting on an object, determined by its magnitude and direction (e.g., $20\,\mathrm{N}$ to the right).
