The discussion revolves around interpreting a motion graph, specifically identifying sections that represent different types of motion such as acceleration, deceleration, and stationary periods. Participants are exploring the characteristics of a graph depicting constant velocity and how it contrasts with other types of motion.
The discussion is active, with participants questioning each other's interpretations and definitions. Some guidance has been offered regarding the characteristics of constant velocity graphs, but there is no explicit consensus on the interpretations of the graph sections or the definitions being discussed.
Participants are working with a graph that is not visible in the thread, which may lead to varying interpretations of the motion described. There is also mention of multiple possible answers provided in the original problem statement, contributing to the complexity of the discussion.
well since the distance is changing over time, that must imply that the object is moving hence for t= 0-2 it is accelerating. Now for t=2-4 distance is not changing therefore it must be stationary. for t=4-5 and t=5-9 the object is accelerating but the first interval (t=4-5) is accelerating faster than the other (t=5-9) . My confusion is that they had provided other possible answers which i have stated, but i can not see any constant acceleration in that diagramDoc Al said:
Yes, during that time the object is moving. But moving does not mean accelerating. What's the definition of acceleration?_Reza_ said:
the rate of change of velocity over time, does that mean the object is moving in constant speed?Doc Al said:
Exactly!_Reza_ said:
Graph that shows distance and time, so distance/time= constant speed. so the different intervals were the distance is changing, is the objects always at constant speed?Doc Al said:
Tell me what such a displacement vs time graph looks like. Would it be straight lines, curved lines, flat lines, what?Doc Al said:
