Introduction to Velocity and Speed and the differences between the two.

[@robertstrickland4594]

If you were my teacher all year, I would be getting a 5 on this AP Exam.

[@FlippingPhysics]

Robert Strickland Thank you for the compliment. I wish you luck on the AP Exam!

[@robertstrickland4594]

Flipping Physics I watched all of your videos the week before the AP Exam and I feel like I got a 4. Your videos really helped me and my friends, and thanks for wishing me luck!

"I enjoyed learning with you". Such an epic line to say to your students along with an amazingly delivered lesson. By the way, a question for you Mr.P, who is the best student among Billy, Bobby and Bo?

[@a1707]

People underappreciates this channel doe

[@Floppeh]

This is really well done. Really explains things thoroughly and points out common mistakes. It covered everything it could have, nice.

[@FlippingPhysics]

Thanks. It's nice to be appreciated.

[@RoXon007]

What a great way of teaching physics. You answer the question which raises in student mind like a me regarding the particular topic.thanks for video

[@jacksonwilkerson5365]

cant belive more people don't watch you this content is great and I've already learned so much thank you man

[@FlippingPhysics]

I know how you feel

[@emmamanning8263]

used this in my physical science class. Loved it..

[@FlippingPhysics]

Thanks! Keep using them, eh.

[@zombienator500]

This guy is great. Helped a lot starting off in physics this year. Keep it up!

[@eoo37]

When I calculate velocity, I continuously forget to write direction. I've to be careful not to miss this. And this video is helpful too. thank you Mr. P.

[@FlippingPhysics]

Don't worry I will continue to remind you. And I will continue to show my work, which will help as well!

[@nicolehales1]

Very helpful. Goofy enough to help me pay attention, too. Thanks guy!

[@ShermukhammadKarimov]

great lesson! thanks for making this video

[@raizzellsantina471]

Thank you for your videos it helps me a lot to improve my skills🤗💖

[@FlippingPhysics]

You are very welcome. Keep practicing, my friend.

[@RogueIntel]

You won't believe what my physics teacher said today..He said speed and velocity is same.. I tried to tell him but what can a suggestion of a student do to a teacher...

[@RogueIntel]

That's i like to watch Flipping Physics rather than High School Physics...haha

[@marleigh5606]

1:20 AP environmental science spoiled me. We had next to no math, so ,when we did, even our teacher would do this. It's worth having to break that habit for this year for the double periods of doing nothing but splashing around in a creek for an hour and a half every few weeks

[@babitasharma1709]

At 7:06 you said because the minutes has 2 sig figs we estimate 1.16 repeating to 2 sig figs. But why are we looking at the minutes and not also the displacement which is 1890 meters

[@babitasharma1709]

is it that we only look at the sig figs of the Divisor?

[@arjundan007]

You are really awesome man I loved learning from you you are the best

[@FlippingPhysics]

Thank you so much 😀

[@arjundan007]

I'm using your videos to clear and take knowledge of all the concept of physics

[@arjundan007]

It's very helpful for me

[@camilamendes5902]

This video is so perfectly understandable ! I do have a question but this is not accordance with this video..what is actually initial velocity ( ik this is quite easy kind of question but i do wanna understand ) can u please help me out ? Suppose for an example , a body is thrown with an initial velocity of 10 m/s . Is this velocity obtained just after throwing or was it already 10 m/s ? And again when it is said that initial velocity is 0 ! What does this mean again ? What actually is initial velocity ? I have got several minute misconceptions like this related to physics ! Can u please help me out ?

[@bonjour9158]

Initial velocity means starting point is 0, there was no change in position prior to that instance

[@medooobassahi6899]

you are awesome I really enjoyed learning with you thank you so much

[@FlippingPhysics]

+medoOo bassahi You are welcome!

[@artandelectronics3437]

Well understood .My doubt is can magnitude of speed and velocity be equal if we shrink avg velocity to instantaneous velocity such that ds/dt =dx/dt at the small interval of time

[@FlippingPhysics]

The magnitudes of instantaneous velocity and instantaneous speed are the same.

[@wafflesaucey]

Glad my teacher made us watch this instead of some old dude with a powerpoint.

[@bellabursulaya2090]

Great vid! so the definition of speed is distance/time?

[@FlippingPhysics]

+Isabelle Bursulaya Yes. speed = (distance traveled / time elapsed)

[@bellabursulaya2090]

+Flipping Physics Thanks! My teacher told us it was a measure of how fast something is traveling, but that's the same as distance over time, right?

[@FlippingPhysics]

+Isabelle Bursulaya Generally, when some one says how "fast" something is traveling, they are referring to "speed", yes.

[@bellabursulaya2090]

+Flipping Physics thanks for your help! :D

[@jaypradhan515]

i have a doubt, you said that speed and magnitude of velocity will be equal only if the object travels in a straight line but if an object moves in a straight line and then returns back to its initial position then its velocity will be zero as its displacement is zero but then its speed won't be zero yeah ?

[@FlippingPhysics]

When an object returns back to its original position, the displacement of the object is zero and therefore the velocity of the object is also zero. The distance traveled by the object will _not_ be zero, therefore the speed of the object will also _not_ be zero. Therefore, the magnitude of the velocity of the object will _not_ be equal to the speed of the object. This video might help as well: kzbin.info/www/bejne/bnK6p4isfdGjmbM

Thanks a lot Flipping physics !

[@kirtikumarmistry8883]

You are perfect.....

[@FlippingPhysics]

Nah But it's nice to know you think so

[@roshanbeeram378]

I have a question will direction of displacement change in velocity

[@FlippingPhysics]

Just so you know "Can direction of displacement change in uniform velocity" is very different than "will direction of displacement change in velocity" which is not really a question and I am not really even sure what it means. Velocity is a vector. A vector has both magnitude and direction: www.flippingphysics.com/vectors-and-scalars.html The direction of velocity will change if the object is turning, therefore, there will be a change in velocity: www.flippingphysics.com/centripetal-acceleration.html

[@artandelectronics3437]

@roshan beeram yes the direction of displacement may change incase of instantaneous velocity but in average velocity the direction of displacement won't change

[@MaheshWari-f7g]

Why "oh noo"? The physics hasn't changed.
