An object is moving with constant non-zero acceleration in the +x direction.The position versus time graph of this object is
A)a horizontal straight line.
B)a vertical straight line.
C)a straight line making an angle with the time axis.
D)a parabolic curve.

Question

Quizplus · Accepted Answer

Since the object is moving with constant non-zero acceleration in the +x direction, its position versus time graph should be a parabolic curve according to the kinematic equation x = 1/2at^2 + vot + x0, where x is the position, t is time, a is the acceleration, vo is the initial velocity, and x0 is the initial position. The term 1/2at^2 is the quadratic term that results in a parabolic shape.
