for anyone who is somewhat confused on the difference between velocity(vector) and speed(scalar) ; here is what helped me understand it: if you are in your car and you start driving forward at 60 mph, that's your speed. and if you stop then quickly reverse to thirty miles per hour you are going backwards, but you don't have a Negative speed, just a speed, no matter what direction it is in. however if you do the same thing and plot it in a Position Vs. Time graph you will see it going in a negative direction, indicating it is returning to the direction of the origin. long story short vector quantities such as velocity help people understand the rate at which something moves, but also its direction and meaning.

[@a_j_all_day7382]

I'm still confused but that you

[@nightfox380]

@@a_j_all_day7382 Velocity requires direction (some people word this as "velocity depends on position" meaning the object's point of origin -- imagine a graph and start at zero); speed doesn't. As a result, velocity can be a positive or negative number. Going backwards? Negative velocity. Going forward? Positive velocity. Positive or negative, it doesn't matter because you're still in motion. Speed, on the other hand, is strictly positive. Once your speed is at zero, you're no longer in motion.

Great explanations thank you. I have a great teacher, but due to time restrains he can't teach everything step-by-step, and having Mr. Anderson (sorry if I spelled it wrong), explain why something is the way it is really helps me understand the more complicated problems.

That was extremely helpful. I've been trying to find out for weeks why velocities are squared. Now the kinetic energy and Einstein's E=mc2 equations make perfect sense. So 1m/s^2 = 1(m/s)/s. Thanks for elucidating that for me.

I always failed my Pure Physics exams like 3 exams straight from January till now without a single exam passes... Until I met ur channel through my chemistry teacher whom showed us ur video on calculating moles and here I am watching this physics video on velocity which I sucks the most and guess what?! I UNDERSTAND so much better than my teacher and plus my mid-year exams the 1st out of second most major exams is around the corner like next week, makes me well prepared after watching ur videos

Hello Mr. Anderson, it seems in this ur examples of velocity is like u ar talking about speed and distance which are scalar but u keep on talking about velocity which goes with displacement. I really respect u and ur presentation please I need clarification on this matter. You are really one of my mentors

i got a question. According to the question at 8:20 ,what is the direction for the velocity?

[@superbrownboy777]

Mr Anderson you truly are a really great teacher but if the object is moving downward isn't it a negative sign and a positive for the opposite?

[@deannayoung1612]

When objects fall it's not because of gravity. It's due to density. If something is heavier then the air it falls down. If its lighter then the air it'll float. As we've all been taught. Buoyancy, density & water surface tension are very interesting. Anyone who isn't familiar should try to check it out sometime.

[@tyyyy95]

Mr.Anderson where did you get the results for each segment of the 2008 olympic 100m finals? I wanted the same breakdown of the 9.58 race?!...its for a physics project on motion and Graphs

[@JazziHD]

+Bozeman Science correct me if i am wrong but i think i can see two problems here one your saying V equals acceleration which i don't think is correct and 2 metres per second should be metres per second SQUARED since it is acceleration

[@silentelysium]

Hi Mr Anderson! I'm not from the US but I find all your short videos helpful with revising these basic first-year university concepts. I know you're doing videos of physics topics (like this one) but are intending on publishing videos about electric fields, capacitors and lenses?

[@elizabethbarron2330]

Helpful! But on the car problem, how did you convert 60 to 26.9 m/s?

[@thunsario]

+Elizabeth Barron He used the conversion miles to hour to meters per second. First start with what your given 60miles/1Hour then using the conversion 1mile=1609.34meters get your meters value. Next convert with 1Hour=3600seconds. then simplify the fraction 96560meters/3600seconds and you get 26.9M/s

[@minibazz]

Hello, just a quick question how come you didn't get 16.6 m/s for the last question and you said it was 26.9m/s (the conversion of 60km/h) because didn't you have to divide it by 3.6? I am probably wrong but just asking.

[@ThinkOutside07]

Sorry my English is not so good, what is the diffrence between speed and velocity?

[@Tavi_186]

really good. respect. and thanks

[@Lancelot885]

Speed is a scalar quantity(These means its just a magnitude) while.Velocity is a Vector quantity. Velocity=Speed and its Direction. Here we are just assuming we are moving in a positive direction

[@amrutvani2]

A few years back, an American spaceship to Mars, had failed just due to poor synchronization of metric and imperial measuring systems ... very sad indeed ! And yet its is mind boggling why Americans even today are still so adamant about not making peace with the metric system !!

[@Patronesofly]

Im just learning this for fun but how did you convert miles per hour into meters per second

[@catjunior1]

km/ hour divided by 3.6 gives you m/s m/s multiplied by 3.6 gives you km/h

[@Patronesofly]

Allie R after the video I found out for every mile it is 2.6.... Metere per sec

[@catjunior1]

Oh sorry, I gave you km/h! Not miles, sorry!
