A ball is dropped and its displacement versus time graph is as shown (Displacement $x$ from ground and all quantities are positive upwards).
$(a)$ Plot qualitatively velocity versus time graph.
$(b)$ Plot qualitatively acceleration versus time graph.
It is clear from the graph that displacement $x$ is positive during motion. Ball is dropped from a height and its velocity increases in downward direction due to gravity field. In this condition $v$ is negative but acceleration of the ball is equal to acceleration due to gravity i.e., $a=-g$. When ball rebounds in upward direction its velocity is positive but acceleration is $a=-\mathrm{g}$. $(a)$ The velocity-time graph of the ball is shown in fig. $(i)$.
$(b)$ The acceleration-time graph of the ball is shown in fig. $(ii)$.
Draw the $x\to t$ graphs for positive, negative and zero acceleration.
A particle of mass $m$ moves on the x-axis as follows : it starts from rest at $t = 0$ from the point $x = 0$ and comes to rest at $ t= 1$ at the point $x = 1$. No other information is available about its motion at intermediate time $(0 < t < 1)$. If $\alpha $ denotes the instantaneous acceleration of the particle, then
Velocity-displacement graph of a particle moving in a straight line is as shown in figure
Position time graph of a particle moving along straight line is shown which is in the form of semicircle starting from $t=2$ to $t=8 \,s$. Select correct statement
The velocity- displacement graph of a particle is shown in figure.
$(a)$ Write the relation between $v$ and $x$.
$(b)$ Obtain the relation between acceleration and displacement and plot it.
