Question

In a position time graph, a curved line represents: acceleration no movement constant velocity

Answer 1

Answer:

acceleration or a deceleration

Explanation:

The gradient of a position -  time graph represent the velocity.

a straight line indicate a constant velocity (gradient ≠ 0)

when it is a parallel line to the time axis , it indicated no movement

when it is a curved line it indicates a changing velocity (either acceleration or a deceleration) as mentioned in the graph
