Velocity-displacement graph of a particle moving in a straight line is as shown in figure
magnitude of acceleration of particle is constant
magnitude of acceleration of particle is increasing
acceleration versus displacement graph is straight line
acceleration versus displacement graph is parabola
The velocity $(v)-$ time $(t)$ plot of the motion of a body is shown below:
(image)
The acceleration $(a)-$ time $(t)$ graph that best suits this motion is :
The diagram shows the variation of $1 / v$ (where, $v$ is velocity of the particle) with respect to time. At time $t=3\,s$ using the details given in the graph, the instantaneous acceleration will be equal to $...........m/s^{2}$
The graph shows the variation with time $t$ of velocity $v$ of an object moving along a straight line. $a-t$ graph will be
$Assertion$ : A body with constant acceleration always moves along a straight line.
$Reason$ : A body with constant acceleration may not speed up.
A particle moves towards east with velocity $5\, m/s$. After $10$ seconds its direction changes towards north with same velocity. The average acceleration of the particle is
