MCQ
The accelerated motion of a body changes due to change in:
  • A
    Speed
  • B
    Direction of motion.
  • C
    Velocity.
  • All of the above

Answer

Correct option: D.
All of the above
The accelerated motion of a body changes due to a change in speed, direction of motion, velocity.
As acceleration posses magnitude and direction. Its magnitude changes by a change in speed, velocity, and direction can be changed by the direction of motion and velocity.
