Acceleration vs time question

  1. Sep 16, 2014 #1
    If the position versus time graph describes velocity and if the velocity versus time graph tells acceleration..
    In acceleration versus time graph, it describes a jerk(rate of change in acceleration)..



    Do you have any idea why acceleration is not constant?
    Are there any factors involved?

    It just means that the net force is not constant. Something happens that changes the net force

    In future, please use the homework posting template provided when you begin a new thread in the homework section of Physics Forums. This is a requirement.

    What basic formula do you know that involves acceleration? (hint: think of Newton!).
