There are two very important errors in your video. First, you state that delta x is a distance. However, delta x (x final minus x initial) is a DISPLACEMENT. If you leave home and go to the store and return home, your delta x and your displacement is zero, but you definitely traveled more than a zero distance.

[DrReinisch]

Also, you state that acceleration is only speeding up or slowing down. That is also wrong. An object going around a circular track at a constant speed (not speeding up and not slowing down) is accelerating. So, acceleration is ALSO a change in direction. These points are important for anyone studying physics to understand -- and definitely more important to memorizing equations.

i found waldo from 1:46 to 2:03 =D

the acceleration unit is wrong. it's to the power of -2 not positive 2. and its not meters per second squared. it's meters per second per second. (:

is that kevjumba music?

You made an error with your accelerating balls example. The balls should both have negative acceleration because gravity pulls them down, so there should never be positive acceleration when it comes to gravity.

That was very helpful thanks alot for the nice video !!

@XSuperFistX saying change is displacement(motion in straight line)

[DrShavargo92]

helping me with physics class! thanks!

nice effort
