It is because you are dividing speed which has units of meters per second (m/s) by time, which in this example is in terms of seconds (s). So if you just look at the units portion of this you have (m/s)/s which could also be written as (m/s) ÷ s. As you may know, when dividing a fraction by another fraction that is the same as multiplying the first fraction by the reciprical of the second fraction. In this case the seconds we are dividing by are not written in the form of a fraction but could be expressed in the form of a fraction by putting s over 1 (s/1). The reciprical of s/1 is 1/s. So (m/s) ÷ (s/1) can be changed to a multiplication of (m/s) x (1/s). In multiplication of fraction you multiply the to numerators to get the numerator of the answer and you multiply the denominators to get the denominator in the answer since m x 1 = m, you get m in the numerator and since s x s = s² therefore (m/s) x (1/s) = m/s². Note that this is NOT (m/s)² which is the same as m²/s². I didn't think this distinction was clear in the video, but only the seconds in the denominator are squared, not the whole fraction. The reason that the units of acceleration are written as m/s² is because acceleration is the rate of change of speed with respect to time. So it is telling how much your speed (m/s) is changing per unit of time (s).
Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Was this answer helpful?
Bro is gonna save me from the science exam ❤
Beo sounds like Saul goodman 💀
Fr 😂😂
Thanku sir.. I've been struggling a lot to understand this..good thing i clicked this video....❤️❤️
Glad to hear that
I will have a report about acceleration and I don’t understand it but this helped me a lot!
Very very good loved it so much 😊
Sir u voice is impressive and best for angering 😊😊
Here for school. Thanks for the information!
i learned a lot thanks♥️
Good to hear. Honestly A kind word is always nice to see.
Where did you get “East” in the last one???
superb work!!!
Thank you
Ayy very good video 👍🏻👍🏿
agreed 👍🏿
Yes
This is the new group chat
Ok
🗣️🗣️🗣️🗣️👧🏻👅👁️👅👁️👅👁️👅
Thankyou ✨
best video sir
best vidoe eVeEeeEr
accidentally clicked on this, got fallen kingdom vibes from the music, and your voice sounds like skeppy
Yeah it does sound like skeppy
are u stupid?
Question is why do I need to calculate acceleration in the first place?
For exam
The car at 1:26 is moving from the East to the West, shouldn't the acceleration at 1:45 be 2 m/s^2 West? Or the animation is just flipped.
dude your soooooooo COOL! :)
his soooooooo cool what?
Thankyou VM ❤❤❤
You're welcome 😊
i loved your video bro why should i suscribe and share only i will like it too
i learned alot thx
Negative acceleration is NOT officially called "deacceleration" in physics.
Thanks for the feedback
Even worse is that the video says a "decrease IN acceleration". What was meant was a decrease in SPEED.
yeah, accelerating in the negative direction would be a negative acceleration, even tho you are technically 'accelerating'.
I am not able to understand why the second has a square ? Please tell

Why is acceleration squared
Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Was this answer helpful?
There is no direction then why the answer is .83m/s^2 to the west
Your voice was breaking sir😞😞
why am i here?
im here cuz im doin a sience worsheet lol
8 de je kralj
:) :)
Sachin se to bole le
this is comment 19
No ur 27
HEY MARK THIS SUCKS
OK NOT MARK
You suck
who is mark??
thank you
