You have 2 things - velocity (aka speed) and acceleration. Speed is a constant linear concept. For instance ... you are traveling at a steady 100mph is talking about speed.
Acceleration is the rate at which speed increase over time.
So if you increase your speed from 100mph to 150mph in one minute, then you are accelerating at an average 50mph per minute.
Acceleration of acceleration just means higher levels of acceleration. So in this example you may have accelerated gradually to begin with and much more at the end. Your peak acceleration will be when the rate of change of velocity over time was greatest. I think this is what you are calling jerk. |
holly shit, please go back to physics class man
