**Teaching notes:**

- There must be a reference point to describe the position of the given body.
- Distance ≥ Displacement.
- Distance is a scalar quantity and Displacement is a vector quantity.
- The physical quantities which are described by only magnitude are called scalar quantities.
- The physical quantities which are described by both magnitude and direction are called as vector.
- Average velocity = (Total dispalcement)/(Total time.)
- Instantaneous velocity is defined as the velocity at that particular time (second).
- When the velocity of a body decreases with time, then acceleration is called retardation or negative accelearation.
- The acceleration of a freely falling and vertically projected bodies is called acceleration due to gravity.
- The value of acceleration due to gravity changes w.r.t height, depth , at equator and at poles.
- The standard value of acceleration due to gravity on Earth is 9.8 m/s2.
