Question

If a particle is moving along a straight line, then it is compulsory to consider direction of initial velocity as positive direction.

• A. True
• B. False

Answer 1

The correct option is B False

Initial Velocity:

1. It is the velocity at the time interval $t=0$
2. It is represented by $u$.
3. It is the velocity at which the motion starts.
4. It can be positive, negative, or zero depending on the coordinate system chosen to define the position.

For a particle moving along a straight line:

1. A particle can move on any side of the origin, so the direction of initial velocity can be positive or negative.

Hence, the given statement is false.
