What can be the angle between velocity and acceleration for the motion on a straight line? Explain with an example.
(N/A) For motion in a straight line,the angle between velocity and acceleration can only be $0^{\circ}$ or $180^{\circ}$.
$1$. If the angle is $0^{\circ}$,the velocity and acceleration are in the same direction,which means the speed of the object increases (accelerated motion).
Example: $A$ car starting from rest and speeding up in a straight path.
$2$. If the angle is $180^{\circ}$,the velocity and acceleration are in opposite directions,which means the speed of the object decreases (retarded motion).
Example: $A$ car applying brakes while moving in a straight line.

Easy
View SolutionThe acceleration of a particle which moves along the positive $x$-axis varies with its position as shown in the graph. If the velocity of the particle is $0.8 \ m/s$ at $x = 0$,find the velocity of the particle at $x = 1.4 \ m$ (in $m/s$).

View Solution$A$ particle moves along a straight line such that its displacement at any time $t$ is given by $s = (t^3 - 3t^2 + 2) \, m$. The displacement when the acceleration becomes zero is ........ $m$.
Medium
View SolutionThe position,velocity,and acceleration of a particle moving with a constant acceleration can be represented by:
The motion of a particle along a straight line is described by the function $x = (2t - 3)^2$,where $x$ is in metres and $t$ is in seconds. The acceleration of the particle at $t = 2 \,s$ is (in $\,m/s^2$)
