Question

define accilaration with example give its SI units

Answer 1

Answer:

The rate ,of change of velocity is called acceleration. Its SI unit is m/s^2

Explanation:

E.g

A body starts with a velocity 10 m/s and attains a velocity of 20 m/s in 5 seconds.

then acceleration is given as

(v - u)/t

Here it is:

(20 m/s - 10 m/s)/5s

= (10 m/s)/5s

= 2 m/s (/s)

= 2 m/s^2

= 2 ms^-2
