How Do You Convert Between Position/Time and Velocity/Time Graphs?

AI Thread Summary
To convert a Position/Time graph into a Velocity/Time graph, the gradient of the Position/Time graph represents the velocity at that interval. Conversely, to convert a Velocity/Time graph into a Position/Time graph, the area under the Velocity/Time graph during a time interval gives the displacement. Understanding these concepts relies on the definitions of velocity and calculus principles, where velocity is the derivative of position and position is the integral of velocity. Simplifying these concepts may help those struggling with the material. Mastering these conversions is essential for grasping motion analysis in physics.

So i am in Grade 11. I have the worst teacher in the school, she cannot teach 4 ****. I need to know how to do you convert a Position/ Time graph into a Velocity/ Time graph and how do you convert a velocity/time graph into a position/time graph?

- PLz if someone could help me out with this. I would greatly appreciate it

maybe your teacher just doesn't know how to relate the material to you.


But anyhow use the definition of velocity to help with conversion.

The gradients in a position (displacement)/time graph gives the velocity in that interval.

The area under the graph in a time interval in the velocity-time graph gives the displacement.

bro no one in the class understands it.. n can u explain in simpler terms

Read this http://www.physicsclassroom.com/Class/1DKin/u1l3a.cfm" . I can't really explain it properly without an example.

From the definition of velocity, the graph of the velocity is the graph of the derivative function of the function giving position as a function of time (just like the graph y = 2x is the graph of the derivative function of the function f(x) = x2). You should be familiar with doing this from your first calculus class.
Likewise, position is the integral of velocity over time (otherwise known as the area under the graph of velocity as a function of time from 0 to t). Likewise, creating an approximation of this graph based on the graph of velocity versus time should be familiar from your calculus course.
If you are sketchy on the details, http://people.hofstra.edu/stefan_waner/Realworld/calctopic1/derivgraph.html may jog your memory.

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 .
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...
