NEET Physics Speed & Velocity MCQ Question
Which of the following statements about speed and velocity is correct?
Speed is a scalar quantity and is always positive.
Velocity is always negative when speed is decreasing.
A particle can have positive velocity while moving in the negative direction.
Acceleration and velocity always have the same sign.
