MCQ
  1. y = constant: Uniform motion
  2. a = constant: __________
  • A
    Non-uniformly accelerated.
  • B
    Uniformly accelerated.
  • C
    v = 0 at, t = 0.
  • D
    Circular motion.
✓

Answer

  1. v = 0 at, t = 0.

Explanation:

No, when a body is under uniform acceleration doesn't mean that it is under uniform motion. Uniform acceleration means, that the velocity of body is changing with a constant rate. Uniform motion is the kind of motion in which a body covers equal distances in equal intervals of time. It means that speed is constant.
