When a car is moving with constant acceleration, the shape of velocity time graph is:

Correct answer: C. Straight line

  • A. Parabola
  • B. Incline curve
  • C. Straight line
  • D. Decline curve

Explanation

With constant acceleration, velocity changes by equal amounts in equal times, so the velocity time graph is a straight line whose slope is the acceleration. A parabola is the shape of the displacement time graph for constant acceleration, which is the usual mix up.

About Acceleration

Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
