Question

Define uniform speed and average speed .State their SI units ?

Answer 1

Uniform speed: It is defined as if an object covers equal distances in equal intervals of time .

1. ‘t’ is also known as constant speed .
2. Uniform speed is not a common phenomenon.
3. SI unit of Uniform speed = $\frac{metre}{second}or\frac{m}{s}$.

Average speed : It is defined as the ratio of total distance covered to the total time taken .

1. Average speed =$\frac{Totaldis\tan cecovered}{Totaltimetaken}.$
2. V _avg = $\frac{s_{1+}{s}_2+s_3+.....}{t_1+t_2+t_3+.....}$
3. The SI unit of average speed is $\frac{m}{s}$.
