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 head-to-tail.
-
- . . .
-
- . . .
-
- From 6.1: Adding scaled vectors head-to-tail.
-
- . . .
-
- 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 vis-viva.
-
- 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.
