Circular Motion: Acceleration (Angular, Tangential, Centripetal)

In this video we will learn the difference between angular, tangential, and centripetal acceleration. We will learn the equations for each and then learn how to use the equations to calculate acceleration.

my biggest problem with centripetal acceleration is that it has different names depending on the class or problem. It is also called Normal and Radial. Teachers need to let us know that they are all the same thing. This information at the beginning of my studies would have help my learning curve greatly.

[@kolwaski8235]

radial , cen acc same, but normal is said when other components come like friction.

[@junior5146]

I've tried to understand the difference for almost an hour. 30 seconds into your video and I got it. THANK YOU!

[@ndog37]

So much easier to understand than my physics professor! Thanks!

[@naveenrawat6278]

hey what do u have at top right corner of ur profile picture ...lol i thought it was a fly on my screen ......

[@OwensStudent-ch3rt]

My professor makes it seem so complicated, but you bring it back down to Earth. Thanks.

[@TheScienceClassroom]

This is a pretty tough concept. I'm glad this video made it more clear for you!

[@nissisantho9951]

really awesome .....perfect and clear.....thank a lot

Thanks love this!

[@hassansalman6901]

Tangetial and cemtripwtal acceleration both are linear acceleration or angular?

[@ballistikmnky9045]

Canada?

Why does angular acceleration point outwards like that? I don’t get that

[@Scorp9031]

it's an axial vector. we denote axial vectors as circular arrows around a point. but this doesn't mean that it is acting in that direction. the actual direction of an axial vector can be found using the right hand thumb rule. curl your fingers in the direction of the circular arrow and the direction of your thumb is the direction of the vector. regardless, it can be hard to visualize

[@muneebkhalidbajwa111]

Centripetal acceleration and angular acceleration are same thing or different?

[@Scorp9031]

different. angular acceleration is the rate of change of angular velocity with respect to time while centripetal acceleration is what causes bodies travelling on the circumference of a circular path to be pulled in

[@verasguilherme]

I still don't get it. What is the difference of angular and centripetal? Both of them are responsible to change the particle trajectory constantly. Can i use angular motions formulas for centripetal as well? thank you for the video tho. Love it.

[@BorisRStein]

The main difference bettween angular acc and centripetal aka radial acceleration is to what unit of measure you are calculating its instant change rate. It sounda like jargon, but in a nutshell, in angular acceleration you measure it in radians/s² and it points in the Z axis; while in centripetal/radial acceleration, you measure it in meter/s², and you can see the difference in both because centripetal acc is V²/r (Note that the velocity is written as V because it is the tangential one, measured in mts/s) while the angular acc is dw/dt (Here, velocity is written as w because it is the angular one, measured in radians/s).

[@BorisRStein]

You are correct by stating that both of them are ways to express the change of the particle trajectory, but one relies on the Z axis (tridimensional) while the other remains bidimensional. That is also the reason we use the "right hand rule" for angular acceleration.

[@jacobvandijk6525]

Why a change in angle is denoted with a delta, and why a change in time is NOT denoted with a delta is beyond me!

[@yahyawasim1994]

For any future viewers: You can think of it like, /T means "over the course of X, where X is T (Time)", hence time is not changing as it will take the object a fixed amount of time in UNIFORM circular motion to complete one revolution around the circle.

where the hell is the freakin volume

Who else in this bih cuz of Mrs. Scott?
