In summary, a student studying in Hong Kong is seeking help with converting a graph to a v-t graph. They have already completed some steps and are asking for confirmation. They also mention confusion about the terminology used for graphs in Hong Kong. Another user points out a potential mistake on the graph and asks about the slope in a specific time frame.

Homework Statement
hi everyone. i am a student studying in hong kong and i have problems when i am preparing for my studies in this summer vacation. My tutorial lesson teacher gave me this graph and told me to convert it to a v-t graph.

i have done several steps and i am wondering if i am having a good start. Can you draw me a correct answer over here? I am really grateful for your help! Thanks!


*(A,B,C,D,E,F,G) are just points, they can be ignored.

There is a problem on your c-d pencil line on what I assume is your velocity v. time graph.

It also looks like you have an S written on the y-axis of the graph drawn in pencil?

This also probably belongs in the introduction to physics section. I don't know if the moderators move these threads.

in hong kong we called d-t graphs as s-t graphs (as i know)

sorry that's wrong. the graph below is a v-t graph

ok then...

Do you see what is wrong with the c to d line drawn on your s-t graph?

s for speed... ?If it really is a v-t graph, then the slope is important, it indicates direction.

Is the slope of your d-t graph + or - in the c-d time frame?
 

FAQ: Converting d-t graph to v-t graph

What is a d-t graph and a v-t graph?

A d-t graph, also known as a position-time graph, shows the relationship between an object's position and time. A v-t graph, also known as a velocity-time graph, shows the relationship between an object's velocity and time.

How do you convert a d-t graph to a v-t graph?

To convert a d-t graph to a v-t graph, you need to take the slope of the d-t graph. The slope represents the velocity of the object at that particular time. The steeper the slope, the greater the velocity. You can then plot the velocity values on the y-axis of the v-t graph and the time values on the x-axis.

What information can be obtained from a converted v-t graph?

A converted v-t graph can provide information about the object's velocity at different points in time. It can also help determine if the object is moving at a constant velocity or if it is accelerating or decelerating.

Can a d-t graph and a v-t graph be converted back and forth?

Yes, a d-t graph and a v-t graph can be converted back and forth as long as the original data is accurate. To convert a v-t graph to a d-t graph, you need to find the area under the curve, which represents the displacement of the object at a particular time.

What are the limitations of converting a d-t graph to a v-t graph?

Converting a d-t graph to a v-t graph can only provide information about an object's velocity at specific points in time. It cannot accurately represent the object's velocity at every moment in time. Additionally, if the data used to create the d-t graph is not precise, the converted v-t graph may not accurately represent the object's motion.
