Motion Graphs: Transforming Position to Velocity to Acceleration vs Time

In this video I will show you how to convert the position vs time graph to the velocity vs time graph to the acceleration vs time graph. The slope of the line on the position vs time graph is equal to the velocity and the slope off the line on the velocity vs time graph is equal to the acceleration.

    THANK YOU SO VERY MUCH. I experienced loads of difficulties lately to understand these 7 types of 'confusing' graphs and You, Sir made it crystal clear in just 17 minutes. Hats off to YOU.

    The slope is increasing because the curve is getting steeper over time. As I like to tell my students imagine standing at the top and then sliding down the curve. The curve gets steeper over time. Also the slope is negative. Does that help?

    The idea showing the relationship among position velocity and acceleration is great. However to explain this with no reference to the actual movement of the car backing up, slowing or speeding up is like teaching to a parrot. Pls fix this and then it is excellent.

    I watch your videos and I have subscribed too, but I am always very uncomfortable with your accent. You regularly do contractions and reductions and quite often your words sounds unfamiliar to me at first hearing. I listen it two or three times, only then I catch your words. Please speak bit slow and avoid reducing words. Pronounce them in full. Being Asian, I am unable to understand those reduced words you utter. Hope you understand my problem and ll cooperate.
