★ Formula for acceleration:-

$\boxed{a = \frac{v - u}{t}}$

where,

• a = Acceleration,
• v = Final velocity,
• u = Initial velocity,
• t = Time taken.

About it:-

1. Acceleration is a vector.
2. It can be positive, negative or zero.
3. Negative acceleration is known as retardation or deceleration.
4. Measuring unit - m s⁻².
