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?

Turtle

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..

yarp

Speed part 2…Let me give you some more direction on this!

Speed has categoriesConstant speed

Average speed

Instantaneous speed

Which one did your coaster have?

Is knowing your speed enough?

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?

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…
