Question

A graph with horizontal axis time (seconds) and vertical axis position (meters). An orange line runs straight upward from 0 second zero meters. A concave blue line runs upward from the same point. Maia says that both lines on this position vs time graph show acceleration. Is she correct? Why or why not?

Answer 1

Sample Response: Maia is not correct because a straight line moving upwards on a position vs time graph has a constant slope, so it represents constant velocity. No change in velocity means no acceleration is taking place.

Answer 2

NO

Step-by-step explanation:

A vertical line on a position/time chart represents an infinite acceleration, which is quite impossible within the current knowledge of physics.
