  • OK this will be a little hard to explain on line but......Average acceleration is just the the acceleration at the final point in time minus the acceleration at the beginning point in time divided by the overall change in time. You can calculate the acceleration at any point in time from the graph. The slope of the velocity time graph is the acceleration. Remember the acceleration is the same along any straight line on the graph. Hope that helps.

  • On the position vs. time graph, the slope of the line is the velocity and on the velocity vs. time graph the slope of the line is the acceleration!!!!!!!

  • Since the slope equals the acceleration, it would be the interval with the greatest slope.

  • exactly!

  • Thank you, I am glad you found it helpful.

  • On the velocity vs time graph the distance traveled is the area under the curve, that would be the time (s) x velocity (m/s) = distance (m)

  • Its really sad. This dude is a better teacher than my real physics teacher.

  • I think, I learn more from FREE internet sources like your great video than the expensive college classes.

    Anyways, thanks a lot for your videos!!!

see all

  • idk.im confused

  • @bhswarthout Love the video but - The average acceleration over a period of time is the difference in velocity divided by the time period considered. Just taking the first and last acceleration and dividing by time gives the average jolt or jerk in m/s/s/s assuming it is uniform!

    Thanks for uploading this video, really useful thanks.

  • THANK YOU!! That helps so much!

  • Thank You very Much:)

  • distance vs time graph is the same as distance time graph right?

  • Thank you, thank you, thank you!

  • oh my gosh, thank you so much for this video. you made this so much easier for me!! i think my physics teacher is in her first year of teaching and she does not know how to explain things like this. she gets mad at us when we have questions or don't do well on her labs/quizzes. i wish you were my teacher!!
