Question

4. Mark the incorrect statement for a particle going on a
straight line.
(a) If the velocity and acceleration have opposite sign,
the object is slowing down.
(b) If the position and velocity have opposite sign,
the particle is moving towards the origin.
(c) If the velocity is zero at an instant, the acceleration
should also be zero at that instant.
(d) If the velocity and acceleration have same sign
then the body is speeding up
​
