I WILL ADD CAPTIONS TO PICS AS I GET TIME THIS WEEKEND.


Alex made a Tesla sighting in Norman. I have heard stories of possibly two more.


Ever heard the term “oligarchy”?


So far so good as of Saturday afternoon.


Australia is suffering the worst fires in recent memory. Global Weirding.


A glance at the topics we will attempt to get to 2nd semester.


From 6.1: Adding Vectors headtotail.


. . .


. . .


From 6.1: Adding scaled vectors headtotail.


. . .


From 6.1: The Subway veers left, turns right.


. . .


From 6.1: 10 step component method.


. . .


From 6.1: Equilibrants


Three types of projectile motion.


It’s weird. We don’t really understand why this is true, why does an object in motion remain in motion as a natural state forever and ever with NO CHANGE to its velocity. No . . . it’s not visviva.


why? why? why? Oh well, the fact is . . . there isn’t. Of course this is assuming no air drag.


A good law to know. You can solve A LOT of physics problems using this law.


A shorter more concise version of Newton’s 1st Law.


Strobe light effect. The first ball is not accelerating. The second ball is. We did problems like this last semester.


Voyager is a great example of Newton’s 1st Law. It’s been going since 1977 at 39,000 mph.


Voyager 1


Heading for interstellar space.


. . .


. . .


The record that accompanies Voyager 2.


The first view aliens may have of us. Is that Beyonce and JZ?


. . .


We live in a BIG city! It would be cool to go downtown one day.


6.2 (extra credit front page. Once you determine the g of the planet, you will have to use the modified Newton’s Universal Law of Gravitation. g = G M / d^2 and rho = Mass / vol and vol = 4/3πr^3


. . .


Modified orange and blue equations used in Type I Projectile Motion.


Type I


Sometimes it makes more sense to solve a problem using the cgs system. Just be careful with your g.


6.2.5 in cgs


Students version of 6.2.5


Type II (A & B) involves an angle which means sines and cosines. Yea!


Equations used in Type IIA Projectile Motion.


Cannons in the Revolutionary War.


. . .


on ships. Limited angles. The article said that the range was determined by the amount of gunpowder used which affected the Vo.


limited angles


. . .


ornate cannon barrel.


long bore.


notice the very short barrel and the angle was set at 45°. So the amount of gunpowder was used to determine range. I don’t think the canon on the right would be very effective. : )


Range Equation Derivation


This is a GREAT APP (get the $1.99 version). THis will help you in all you math and science classes for now and into your college years.


DANGER! DANGER! DANGER!


Half the battle in Physics is determining what set of equations to throw at the problem


6.3.8b


6.8.3b: Solve it the easy and safe way.


Spacex through it’s short history. Notice three failures to start the company. Perseverance!


The launch early in the AM Saturday morning.


. . .


The drone landing platform.


What was SUPPOSED to happen. “Close, but no cigar” as Musk said.


Eventually, up to 7 astronauts will ride in the Dragon.
