Question

What do you mean by acceleration ? State its CGS and SI units .

Answer 1

Acceleration:

1. The rate of change of velocity is called acceleration.
2. CGS unit of acceleration is $\frac{cm}{s^2}$.
3. SI unit of acceleration is $\frac{m}{s^2}$.
4. It is denoted by a letter ‘a’.
5. Mathematically it is given as,

$a=\frac{Changeinvelocity}{Timetakenforthechange(Timeinterval)}$

$a=\frac{v_2-v_1}{t}$

Where $v_1,v_2$ represents velocities at two moments.
