Question

Which of the following shows the shape of a position-time graph for an object with constant acceleration?

Answer 1

c

Step-by-step explanation:

The position vs. time graph of an object with constant acceleration is a parabolic curve. The curvature is upward for positive acceleration and downward for negative accelerations.

Answer 2

C

Step-by-step explanation:

The relationship between distance and acceleration is dependent of the square of the time the unit is accelerating: (1/2)*a*t^2, where a is the acceleration and t is the time. Since the time is squared, and it falls on the x axis, each increse in time produces a squared impact on distance.
