Question

how do you find average velocity,average speed and do a motion map?

Answer 1

I'm not sure about a motion map. I've never learned about one. But I know equations for average velocity and speed...

Do you know the difference between velocity and speed?

Answer 2

Nope

Answer 3

Okay! Well, when we're talking about speed, we don't care about direction, but we do with velocity.

It makes sense that roads have a \(\sf speed\) limit. They signs don't tell you which DIRECTION you have to go!! Haha!

When we talk about velocity, we say things like 50 miles per hour \(\sf north\ west\). Or some other direction.

Answer 4

Ok so like on a vector,can i just attach my homework worksheet...

Answer 5

Okay! You can take a picture, put it onto your computer, and use the "Attach File" button below the typing box.

Velocity is a vector, while speed is a scalar, if that's what you were getting to! :)

Answer 6

Lol yeah that's what i was trying to say,it kind of sucks not knowing this

Answer 7

It takes a while to understand it :) Take your time, and learn it when you can!

So, do you know that distance is a scalar, and displacement is the vector version of distance?

Answer 8

No actually i didnt know that,sorry its taking so long for me to attach my homework my webcam made it look backwards

Answer 9

Haha! That's okay! Mine can change that in the settings.

But, when you have the backwards picture, can you flip it around with the image viewer?

Answer 10

I dont think so..lol now its just not even working let me try and find an online version of the worksheet

Answer 11

Okay! Can you post the backwards version?

Answer 12

Took it from my phone and got it on here,sorry if its bad quality

Answer 13

Okay! I can't read any of it, but it seems like the movement is all in one direction or the opposite directoin, huh?

Answer 14

I'm sorry,lol i dont even know anymore but i could try the webcam again

Answer 15

Well, let me let you know how to find the averages!

But first, do you know what the average of some numbers is?

Answer 16

Where you add up all the numbers and divide by however many numbers there are

Answer 17

Right!

So with speed, you add up all of the distances (no direction, so no negative numbers) and divide by the time it took.

With velocity, you add up all of the displacements (so the distances can be positive or negative, depending on direction) and divide by the the time it took!

Answer 18

You don't need to attach the pictures if you learn how to do it in general. Learning how to do it might be easier than getting a good picture, anyway! Haha!

Answer 19

So what if I said that there is a bee that is flying. First it flies 3m to the right in 4s, and then 4m to the left in 5s.

So, try to find the average speed. The total time is the sum of the individual times.

Answer 20

Ok,and what about finding displacement,i tried using the webcam but the whole image was blurry so i broke it up into parts and the parts are not in order so you might have to figure it out,im sorry

Answer 21

That was a good idea, but they still look a little blurry! And backwards, but I think the Paint program could change that...

Answer 22

Can you type any of it out?

Answer 23

I dont know because a lot of it is graphing

Answer 24

Is that sort of what it looks like?
