Question

The velocity-time graph of a particle moving along X-axis is shown in figure. Match the entries of Column I with entries of Column II.

Answer 1

$\left(A\right)$ Since velocity is positive and $\frac{dv}{dt}$ is also positive, therefore, particle is moving in positive $x$ direction with increasing speed.$A\to 1$
$\left(B\right)$Since velocity is positive and $\frac{dv}{dt}$ is also positive therefore, particle is moving in positive x direction with increasing speed.$B\to 1$
$\left(C\right)$Velocity is positive but $\frac{dv}{dt}$ is negative therefore, particle is moving in positive $x$ direction with decreasing speed. $C\to 2$
$\left(D\right)$Velocity is negative and $\frac{dv}{dt}$ is negative therefore, particle is moving in negative $x$ direction with increasing speed. $D\to 3$
