The acceleration \(\vec{a}\) of a particle is given by the following formula,

$$\vec{a} = \frac{\vec{v}}{t}$$

where,

\(\vec{v}\) = velocity of the particle.

t = time taken.

Acceleration is a vector quantity. SI unit of acceleration is metre/second^{2} and its dimensional formula is [ M^{0}L^{1}T^{-2} ].
