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.
