Mark the correct statements for a particle going on a straight line
  • a)
     If the velocity is zero at any instant, the acceleration should also be zero at that instant
  • b)
    If the velocity is zero for a time interval, the acceleration is zero at any instant within the time interval
  • c)
    If the velocity and acceleration have opposite sign, the object is slowing down
  • d)
    If the position and velocity have opposite sign, the particle is moving towards the origin.
Correct answer is option 'B,C,D'. Can you explain this answer?

 Answer :- b,c,d
Solution :- All options are correct except A because, if the velocity is zero at an instant, then acceleration may not necessarily be zero at that instant.
For e.g. when an object is thrown vertically upward, at highest point velocity is zero but acceleration on it due to gravity is non-zero.
Option B is correct as the derivative of velocity will be zero in case velocity is zero for a time interval.

Explanation:

Velocity and Acceleration Relationship:
- If the velocity is zero for a time interval, the acceleration is zero at any instant within the time interval. This is because when velocity is zero, there is no change in the position of the particle, hence the acceleration is zero.
- If the velocity and acceleration have opposite signs, it means that the object is either slowing down (if they are both non-zero) or changing direction (if one is zero). This relationship helps in understanding the motion of the particle along a straight line.

Position and Velocity Relationship:
- If the position and velocity have opposite signs, it indicates that the particle is moving towards the origin. This means that the particle is moving in the direction opposite to the positive direction of the coordinate axis, towards the origin.
Therefore, the correct statements for a particle going on a straight line are:
- If the velocity is zero for a time interval, the acceleration is zero at any instant within the time interval.
- If the velocity and acceleration have opposite signs, the object is slowing down.
- If the position and velocity have opposite signs, the particle is moving towards the origin.
