Position/Velocity/Acceleration Part 1: Definitions

Thank you very much

if you find the acceleration/deceleration confusing, you're not alone. A lot of education places only use acceleration and the direction is indicated by positive or negative. They do this to avoid confusion and even though people are used to the colloquial "deceleration" once you get used to the idea of "there is only acceleration" and the direction is indicated by positive or negative, it can make it a lot easier to keep the directions straight in your head.

But how acceleration is always constant

Thx bro❤

Hi sa mga student dyan ng mambugan . 😘😘😘

hands down the best videos!!! Thank you so much!!!!!!

This was a great video but it did kind of leave me asking myself what displacement actually is. For those also confused it's the position in reference to the origin, so if I travel 4 meters to the right from the bus stop and one meter to the left, the distance traveled would be 5 meters but the displacement would be three meters to the right since that is where you are relative the bus stop (regardless of how you got there).

my best friends sisters uncle's brother took a dump on my lawn, i used this video to accelerate my car into him

666

6

666

get it to 666

6

8

Thank you very much for the amazing explanation!
But may someone explain why for stage c and d(reverse acceleration and reverse deceleration)
For D (Displacement Vector) the direction is Forward instead of backward?
Because I thought you are going back to the original starting point that's why should be backward instead？ Thank you

Jesus is teaching me physics

Thank you so much

what kind of a#%hole would only stop for an animal only if it's your favorite XD

It is amazing video

Displacement for c) and d) should be backward

wouldn't displacement be backwards for c and d is the car is travelling in the opposite direction?

Please Pray that I get a good grade on my physics exam tomorrow !!!!

"like a normal person" 🤨.......am I up normal 😎😏

i love you

c oppotion

it was so helpful

Can we know the distance needed for a car to reach a certain speed from knowing how much time it needs to reach that speed ( for example bugatti the fastest car in the world need 3 seconds to reach 100km/h so i want to know the distance traveled in this 3 seconds by the car ?

Thank you <3

Is Low of acceleration same thing as acceleration?

Honestly, you will save my academic life - I'm doing Biomechanics this semester and in week one, my head is spinning! How do you know so much Professor Dave?!

Easy, precise, and brief. Nice video, worth a year of knowledge

i wish professor dave was my dad lol

I understood more after watching your video.
thankyouu

I see you👁️👁️.............

Thank you so much... :)

Flat Earthers be like: this proves the earth flat
Normal People: Learn Physics

The best explanation video ever

Who else is about to take a physics pre-comp?
just me….?

this explained it way better than my science teacher last year

You said acceleration in opposite directions because velocity increase but in comprehension questions I got confuse

Thank you thank you so much!!!

respectfully you deserve absolute toe-curling, aneurysm-inducing, eye-rolling, spiritual awakening, mind-boggling head. Thank you professor Dave.

Sir, i have a wrong perception with respective direction. Please help me to correct in required places

If displacement is shortest distance between two(A,B) points, it will have single direction A to B
And Velocity is displacement/time

velocity should have single direction. Why it is given as velocity can change by changing direction or speed or both.

Terimakasih untuk Professor Dave dan untuk orang yang menerjemahkan subtitlenya ke dalam Bahasa Indonesia. Salam dari Indonesia.

Thank you professor Dave, your explanation are more helpful in our daily life, you make us understand better what was so difficult to understand ✍️♥️

Now I know, because in computation, I was confused about the difference since velocity and acceleration are both speeds, something like that.
