Particle Motion - Speeding Up and Slowing Down (Example, AP Calculus)
This video works through an example of identifying the intervals on which a particle is speeding up and slowing down. The position function (polynomial) is given for the particle over the time interval, [0, 4].

The algorithm should promote this video more. Very helpful!!
Thank you!!!! I have been stuck on this question for days and the book was SOOOO unhelpful. You are amazing!
You organize your work very nicely. You explain things well and the reasoning. Very good and helpful.
Should have added 'Total Distance Traveled'. Would have been greater. Thanks for the clear narration.
Thank you! You explained it really-really well!
Thank you for this video. This was not included in webassign's example and I was on my last try, with this helping me get it right!
you explained it better than my professor
very good explanation.. others were confusing.. thanks for helping before exam Mr Elliot
Great Video!!!!!!! Thanks so much for the clarity!!!!
Thank you!!!! This is so helpful!!
I love you so much bro thank you
quick question, if the velocity of a particle is 0 but the acceleration is positive would that mean its speeding up, slowing down, or neither?

Remember, a particle is speeding up when the sign of the velocity and the sign of the acceleration are the same (slowing down if they are opposite signs). Zero is unsigned, neither positive nor negative. Which means it doesn’t fit into either of our cases. So the answer is “neither.” Hope that helps!

It means the particle is at rest , and as James sir told
