a = (v - u )/t

Where,

a is Acceleration

v is final velocity

u is initial velocity

and t is time taken.

_____________________

Types :

there are three types if acceleration :

Positive acceleration

negative acceleration ( or retardation )

zero acceleration

_____________________

Its s.i unit is m/s²

Answer 2

of change of velocity of

any moving object.

• Its symbol is 'a'.
• Its SI Unit is ${\mathtt{{ms}^{ - 2}}}$.
• It is a vector quantity.
