Motion notesI hope you aren’t getting “motion sickness already”

Cool coasters huh???Soooo… how easy was it to have
a 5 second run???Is 5 seconds a “long” time?How would you describe the
marble’s motion as it moved through the track?

Let us define somethingSpeed:
2 components of speed:1:2:Units of speed:What is the speed of standing
still?Leonardo

Math time!!!!Units: miles/hourmeters/secondDoes it look like your are “x” or
“÷”Math of speed (write it out man)

Practice, practice, practice (2)
I want practice… gimme!
Practice? I don’t need any stinking practice!

No practice? Weak sauce!Get to work
suckers!NAUGHTY! (2)
You should have done your
homework. Now face…. The shredder!
Moving on suckers

Practice makes perfectGood call
students!A little practice
always helps! (1)
Just two to practice!

Here’s one to try out!What is the
speed of…A marble
moves 10 m in 5 seconds
A person walking 2 meters in 2.5 seconds
Yarp…

More coasters…Yep… let us build this and see if
we can use the math to figure out how fast those marbles are going…
And it is a great way to practice the speed calculation..

Speed part 2…Let me give you some more direction on this!
![Page 11: Motion notes](https://reader036.fdocuments.net/reader036/viewer/2022070423/568166a3550346895dda8e46/html5/thumbnails/11.jpg)
Speed has categoriesConstant speed
Average speed
Instantaneous speed
Which one did your coaster have?
![Page 12: Motion notes](https://reader036.fdocuments.net/reader036/viewer/2022070423/568166a3550346895dda8e46/html5/thumbnails/12.jpg)
Is knowing your speed enough?
![Page 13: Motion notes](https://reader036.fdocuments.net/reader036/viewer/2022070423/568166a3550346895dda8e46/html5/thumbnails/13.jpg)
Velocity = speed + directionVelocity has the same math as
speed but now you tell what direction you are going.
5 m/sec WESTVelocity triangle (draw it in!)

Tri the triangle (triangle on board)What is the
velocity of…A marble going
6 m east for 2 sec?
What is the time a marble has with a velocity of 4 m/sec west and moves a distance of 12 m?

And just one more!!!!What is the
distance a baseball travels with a velocity of 20 m/sec south for 2 seconds?

What’s your vector victor?Vectors are arrowsThe represent lotsDirectionVelocitiesForcesA woo hoo…

What are these vectors saying?
Which one is faster?Which one is more?

Vector mathDraw me some adding vectors
Draw me some subtracting vectors

What is the totalTotal these vectors…
10 m
7 m
5 m
8 m
12 m

Yes…. Practice time…Time to practice…It does make perfect…One assignment..One more coaster… time to
make an experiment…Yarp that

Time to wrap up velocity…
part 3You changed a variable…
How did it change the velocity???

Woa… what are you doing here?Listen up Mr. S… that is found in
the graphs and table section… you naughty…
