What is Vector Acceleration in Physics? (Centripetal, Instantaneous & Average Acceleration) -[1-4-2]

Twitter: / jasongibsonmath
In this lesson, we will learn what acceleration is in physics and how to calculate it. More specifically, we learn how acceleration works in two and three dimensions and it acts as a vector that has magnitude and direction. We will learn that the acceleration is the derivative of the velocity, which is the rate of change of the velocity with respect to time. The change in velocity can be caused by a change in speed or a change in direction of motion. We show how this works in two dimensions. We also examine motion along a circle, which gives rise to centripetal acceleration. In all cases, we can define an average acceleration, and we can take the limit to find the instantaneous acceleration at a point along the motion.

The BEST explanation of the acceleration vector I have watched in my 74 years on God's green earth. I have Jason's physics DVDs, but this explanation far surpasses his DVD version. Absolutely terrific. Just beautiful. I'm going to see if THIS VERSION of his physics course is available for purchase on his website. Thank you, Jason, for an excellent job but even more for a great service.

@@ottofrank3445 Thank you so much - so nice of you to say that!

Superb lesson. Jason deserves a medal for making the subject matter so understandable.

Excellent explanation of how position, velocity, and acceleration are vector quantities, with their directions being important as well. When resolving them into their x-, y-, and z-components, I seem to recall from my college days (a hundred years ago) that the components were treated as vectors themselves by incorporating unit vectors i, j, and k (leaving off the ^'s!). But I've lost some brain cells since then. Thanks Jason for a great lesson.

Thank you so much!

[@jackflash8756]

The way you teach is truly excellent and I wish you were my maths/physics teacher when I was a younger man.

[@tresajessygeorge210]

THANK YOU... SIR...!!!

[@amjaddahabreh2168]

If anyone doesn't get it after all this clarification, take a deep breath and change your direction to another branch of life. Jason, you are amazing and amusing!!!!!!

[@ottofrank3445]

Your physic series are perfect! I am watching every morning when I wake up!

Good Evening Sir from India An IIT Aspirant Sir you are teaching very well in mechanics... Like I have to understand torque, you explained it very well with the example of wrench 🔧.. Now I can relate somethings around me very well or understand.. It's very joyful to me on applying this object.

[@mewsicman9541]

Sir Jason, please make a video about Einstein's theory relativity in a way that an average person can comprehend it

[@MathAndScience]

Definitely one day.

[@anthonygregg862]

another super lesson and great understanding. Congratulations on the 1M. Thankyou sir.

[@MathAndScience]

Thank you so much!

[@mohammed-tg5ci]

Fantastic Thank you

[@MathAndScience]

Welcome!

[@sleepdeprived6586]

Thank you so much sir!!You cleared all my doubts i was engaged the whole lecture and couldn't tell when an hour got over. Now i can finally sleep in peace 😁

Congratulations on 1 million

[@MathAndScience]

Thank you I appreciate it!

[@johnnytramazino208]

I’ve been hearing a lot of talk about the law of vibration and sin waves. Wondering if you could explain this phenomenon? Thanks

[@nadiaalhassoun6832]

Thank you so much

[@MathAndScience]

Welcome!

[@ictechpro9192]

Thank you!

[@foronline3722]

Can you please make a video about integration with parts

[@KINGCG10]

Right on time!!!

[@MathAndScience]

Awesome!

[@hanhjuli]

Thanks

[@MathAndScience]

You are very welcome. Thank you so much - I very much appreciate the kind words and donation. Please do stay in touch! Jason

[@moseschikusela9182]

You are great

[@MathAndScience]

Awww thank you!

[@Diiriye14]

Thanks sir

[@eigentheory]

Great!

[@bogus_not_me]

Would it be correct that the force of the change in vector is always perpendicular to the vector tangent in circular motion? (The force turning the wheel is from the axle rotation.)

[@MathAndScience]

Yes that is correct! In circular motion, the force is always acting towards the center. I hinted at this but will emphasize when we get to the dedicated lesson in circular motion.

[@qualquan]

Unduly complicated xmtutor is far better and to the point

[@bogus_not_me]

My physics teachers never allowed "deceleration" - always negative acceleration.

[@MathAndScience]

Agree!
