AI Thread Summary
A velocity-time graph indicates negative motion when the graph lies below the time-axis, representing negative velocity. This suggests that the object is moving in the opposite direction, or "backwards." The graph does not directly show the direction of motion but indicates when a change occurs. A negative value on the graph confirms that the object is reversing its motion. Understanding these graph interpretations is crucial for analyzing motion effectively.

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?

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
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
