Making Inferences From Motion Graphs

[Bashyboy]

The question is: "How can you tell from a velocity-time graph that you are moving in the negative?

I don't believe a velocity-time graph reveals that sort of information. Can't you only determine when the direction of motion has changed?

 

[Bashyboy]

Perhaps you can...Would the answer be that the graph would lie under the time-axis?

If you mean going backwards, your velocity would be negative. Thus you would actually be reversing
