Answer 7

Honestly, you shouldn't expect someone on here to help with lab work as we were not present during the lab nor have the information. Such as your first question, inclination? Your table does not give that. You should be using excel or such to graph these out yourself, I could do that but that will not help you. Try it yourself.

Answer 8

no I do know the inclination its 10 degree

Answer 9

and I did do the lab :/

Answer 10

i just don't know how to find the slope and compare it

Answer 11

What is the slope of a distance vs time graph

Answer 12

thats what idk how to find but I used the website and plugged in the values that I posted and I got 4 vertical lines

Answer 13

I am asking you, do you know what the slope of a distance vs time graph is?

Answer 14

Slope is the change of y of over x, so \[m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} } \]

Answer 15

no I know the formula but wouldn't there be a lot of slopes ?

Answer 16

Ok so let me ask you a simple question, what is the y - axis and x - axis on a distance vs time graph

Answer 17

x axis is the time and y axis is the distance

Answer 18

Good, so the slope is \[\frac{ \Delta d }{ \Delta t }\] what does this give us?

Answer 19

thats where I get lost :/

Answer 20

Look at the units

Answer 21

What are the units for distance and time

Answer 22

1 for x axis and 0.1 for y-axis?

Answer 23

I am asking for the dimensions

Answer 24

It's on your table, look at the titles for the columns

Answer 25

m and s

Answer 26

Yes, now if we look at the slope, what are these units for \[\frac{ m }{ s }\]

Answer 27

average

Answer 28

Those are the units for velocity, if you can recall \[v = \frac{ d }{ t }\]

Answer 29

yes is for average velocity=m/s

Answer 30

You should be able to answer your second question now.

Answer 31

Why or why not? What does the slope of a distance (or displacement) vs. time graph mean?-it means average velocity
