Question

12 multiple choice 0.5 points if a graph is a straight line with constant slope, the motion has: zero displacement changing direction constant velocity constant acceleration

Explanation:

In kinematics, the slope of a position-time graph represents velocity. A straight line with constant slope means the velocity (rate of position change) is unchanging. Zero displacement would mean the object returns to start, which doesn't match a constant slope line. Changing direction would require a slope sign change, not constant slope. Constant acceleration is shown by a curved position-time graph or a straight velocity-time graph.

Answer:

Constant velocity
