Q150

At uniform speed the acceleration is

  1. (a) Maximum
  2. (b) Minimum
  3. (c) ZeroCorrect answer
  4. (d) Constant

Solution.

Answer: (c) Zero

  1. Taken as straight-line motion, uniform speed means the velocity does not change.
  2. Acceleration is the rate of change of velocity, so it is zero.

Trap: In uniform circular motion the speed is constant but the direction changes, so there is acceleration a=v2/ra = v^{2}/r; the question means straight-line motion.
