(1) Intro
(2) Always write down the sign, not only for negative numbers, but also for positive numbers. The kinematics variables and their units
(3) The kinematics variables for the x-component and the y-component
(4) The kinematics equations for the x-component
(5) The missing variables. The kinematics equations for the y-component
(6) The systematic, five-step method for solving kinematics problems
(7) An example, illustrating how to use the systematic five-step method
(8) The example concluded
(9) Another example
(10) The example concluded
(11) Another example
(12) The relationship between velocity and acceleration. Velocity tells you which way you're going. Acceleration does NOT tell you which way you're going; in one dimension, acceleration tells you whether you're speeding up or slowing down
(13) The relationship between velocity and acceleration, continued. When the acceleration is parallel to the velocity, you're speeding up; when the acceleration in antiparallel to the velocity, you're slowing down. "Slowing down" does not mean "negative acceleration"
(14) Don't compare the length of the acceleration vector with the length of the velocity vector. If an object is accelerating to the left, it may or may not be moving left right now; but if it continues to accelerate to the left for long enough, eventually it will indeed be moving left
(15) Summary of the relationship between velocity and acceleration. Don't use the word "deceleration"
(16) An example
(17) The example continued
(18) The example concluded. Constant-acceleration kinematics displays symmetry--if two points on the path have the same displacement, then the object has the same speed at both points
(19) Another example
(20) In the instant that you reverse direction, your velocity is zero
(21) An example
(22) The example concluded
(23) Two more examples
(24) Another example
(25) The example concluded
(26) Another example
(27) The example concluded
(28) "Zero acceleration" means "constant velocity"; in one dimension, "zero acceleration" means "constant speed"
(29) How to solve kinematics problems with constant velocity (zero acceleration)
(30) Constant velocity kinematics, continued
(31) Constant velocity vs. constant acceleration
(32) An example, involving constant velocity and multiple objects
(33) The example continued
(34) The example concluded

Very helpful; thank you mister!

[JustaKarter]

@sealustt There are 34 parts of one-dimensional kinematics ^^

[baydood510]

Do these videos also work for constant velocity?

[changk715]

too slow

[Sagals92]

This guy talks about the most easiest things ever. Anyone who found this really helpful is sad

[Be1smaht]

@MrCollegeEater how so?



[Baleena111]

you have taught me more in the past hour of watching your videos, then my own professor has in the past two weeks of class, thank you sooo much for posting these.

[agilanandy]

AWESOME SIR!

[imakonvict]

Amazing! Thanks a lot!

Thanks Zero from Grand Theft Auto : San Andreas! Jk, these are extremely helpful videos! Sadly, I've discovered these a little bit late into my class, but they're nevertheless very helpful. -And this guy is not a douche bag, he's simply keeping a strict tone so that the lectures sink in effectively. Oh, and I'll be sure to donate as soon as I pay off my loans! : ]
