Define speed. Define average speed.
(N/A) Speed: The distance covered by an object in unit time is called speed. It is defined as the rate of change of distance.
Average speed: The ratio of the total distance covered during a journey to the total time taken is called average speed.
Mathematically,$\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}$.
The $SI$ unit of speed is $m/s$ $(ms^{-1})$,and it is a scalar quantity. Therefore,its value is always positive.

View SolutionThe velocity of an object moving in a straight line path is given as a function of time by $v = 6t - 3t^2$,where $v$ is in $m/s$ and $t$ is in $s$. The average velocity of the object between $t = 0$ and $t = 2 \ s$ is
The position of an object moving along the $X$-axis is given by $x = \alpha + \beta t^2$,where $\alpha$ and $\beta$ are constants with appropriate dimensions and $t$ is time in seconds. The average velocity between $t = 2 \ s$ and $t = 4 \ s$ is $12 \ m/s$. If $\alpha = 8 \ m$,then the value of $\beta$ is: (in $m/s^2$)
