When Acceleration Is Zero in Plane Motion

Practice question

Question

In motion with constant acceleration in a plane, what is true if the acceleration is zero?

Options

Choose one · Correct answer highlighted

The path is parabolic The object stops The motion is circular The motion is uniform and rectilinear Correct

Explanation

If the acceleration is zero, the velocity remains constant in both magnitude and direction, resulting in uniform rectilinear (straight-line) motion. Without acceleration, the object continues in its initial state per Newton’s first law.
