☛Velocity of body defined as displacement covered by it's per unit time.

• $\bf\:velocity=\dfrac{Displacement}{Time}$

• It is a vector quantity.

• SI unit of velocity is m/s

• CGS unit of velocity is cm/s

• It also describe motion.

✵Types of velocity

☛ Uniform velocity:-The displacement covered by the body in the equal interval of time.

☛ Non Uniform velocity:- A body covered unequal displacement in equal intervals of time.

☛ Average velocity:- Average velocity is defined as the ratio of total displacement to the total time taken.

$\bf\:Average\:velocity=\dfrac{Total\:displacement}{Total\:time\:taken}$

☛ Instantaneous velocity:- Velocity of a body at a particular time.

✵ About Displacement

☛It is the shortest distance between initial and Final point of moving object with particular direction.

• It is a vector quantity.

• SI unit of displacement is m.

• CGS unit of displacement is cm.

• Displacement may be positive, negative and zero.
