Blog 5 – Trinomials

This week in pre-calc we learned how to factor using trinomials.

There are a couple steps to figuring this out, but once you have figured it out it is very simple.

  1. identify a,b, and c in the trinomial ax2+bx+c.
  2. write down all factor pairs of c.
  3. identify which factor pair from the previous step sums up to b.
  4. Substitute factor pairs into two binomials.

First Nation Mascots and Logos

 

Racism has been one of the deepest social problems in history, it affects millions of people worldwide. What happens when racism and sports collide? Sports teams should not be allowed to use First Nation’s logos or mascots to represent their team. Sport was made to bring people together, not tear them apart. Hundreds of years ago the olympics were formed to bring nations together.

Schools and professional teams have been using First nation’s logos, mascots, and names for many years. According to American Indian Cultural Support, nearly 2,500 schools across the United States still use Aboriginal-themed team names, logos, and/or mascots. By using First Nations logos and mascots it can be seen as discriminating towards the First Nations community. In fact, they encourage and reinforce negative stereotypes that put down their people and culture. Many sports teams claim that they are honouring the First Nation peoples. Don Marks an editor of Grassroots News, Manitoba’s oldest and largest indigenous newspaper says differently, “You have to hope that they educate themselves and catch up with their leadership” (Marks told Susan G. Cole, Lose those First Nations Logos, nowtoronto.com). Sports teams have a major influence on many children and adults in the world. Jesse Wente a Toronto based-based pop culture critic told CBC, “I do think indigenous logos are racist, because they’re a by product ultimately of colonialism,” CBC Radio’s Metro Morning.

Racism and stereotypes are everywhere. Can we keep them away from something that should bring us together? It can be a fine line between what is offensive and what is sympathetic. By changing the names of these teams allows the perspective and stereotypes of First Nations people to change.

Newtons Law

newtons 1st law-vpj8jt

Newtons 1st law:

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In this video it demonstrates this law; when the ball is moving is continues moving until a force (the hockey stick) is forced  against it.

 

newtons 2nd law-2nsdxzk

Newtons 2nd law:

Newton’s second law of motion shows that acceleration happens when a unbalanced force is applied. When the force is stronger then the friction or force against the object accelerates.  In this video it shows how when the same force is applied to a lighter weighted object it goes faster. The more mass the object has, the slower it will go with the same unbalanced applied force.

 

newtons 3rd law-pufe0c

Newtons 3rd law:

Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. In this video it shows when a force from the ball is applied to the ground an equal force is applied to the ball making it bounce back.

Nuclear Energy

Nuclear Energy 

As or today, nuclear energy is one of the most environmentally friendly sources of energy. Nuclear energy produces very few greenhouse gasses compared to other traditional sources like coal power plants. There is little effect on water, nature, and animals when using a nuclear power plant.

Not only is nuclear energy a healthier and friendly choice, it is also cheaper. Nuclear power plants run on a chemical element called uranium. Uranium is a very heavy metal which has been used as an abundant source of concentrated energy for years. The cost of uranium is very low meaning the cost of running a nuclear energy plant would be low. Even though setting up a nuclear power plant is high, the impact on the cost of power will be that much lower.

Thirdly, a nuclear power plant is very reliable. It is estimated we have about 80 years of uranium. Other energy sources may be reliable on wind, sun, and rain. Nuclear powers plants can run uninterrupted for years. It is believed that uranium will last us much longer than fossil fuels. The best is that the engr. has persistent supply.

Another huge point of interest in Nuclear power plants is that the energy is more proficient; meaning we get more bang for out buck. A lower amount of uranium can still result in a larger supply of energy. Energy released by nuclear fission is approximately ten million times greater than the amount of angry released by a fossil fuel atom.

One many argue that a nuclear energy plant may be dangerous for the civilians around the energy plant, but if you compare the benefits that you are getting to the small risk of a nuclear accident it is not even a question. Nuclear power could solve many health issues just from polluting less.

These are just some of the numerous reasons that multiple nations are putting their resources into creating nuclear power. Some of the greatest benefits of nuclear power are; does not rely on fossil fuels, better for the environment, and is more reliable.

“Dead Poet’s Society” Reflection and Connection

1. Reflect on the meaning of the movie and its connection to “Tomorrow”

Dead Poet’s Society is about a group of boys that go to a private school. While all these boys are very bright, most of them are forced to go to this school by their parents. When the main character Neil finds his real passion of acting he is forced to quit. I believe the meaning of this movie is that you will always be happy when perusing the thing that you love; as well as, life is to short to be protected in your own bubble.  This connects to the poem “Tomorrow” is the area that both the movie and poem are explaining how life is very short, so you don’t want to waste your time.

 

2. Your personal thoughts about the movie

My thoughts on the movie is that it was an all around good movie. I missed the first day of the film, but I was able to pick up on the message. The movie did a very good job at illustrating how doing something you love can change how you act and how you feel.

The Physics of Ancient Inventions 

Ancient Invention: The Catapult 

By: Jaxson Abdou

Date: November 28, 2017

 

History:

During the middle ages many weapons were created to help in battle. The Catapult dates back to around 400 BC, where it was invented the Greek in the city, Syracuse. The catapult was mainly built due to the rising height of castle walls. There are many different types of catapults including: Ballista, Mangonel, and Trebuchet. Our catapult is a Mangonel. During battle different objects were thrown from the catapult, these included: dead bodies, rocks, and later on, grenades.  When first built they were strictly made and used to win battles, but we still use catapults. We do not hurl projectiles at castles anymore, but we do build them to have fun.

 

Physics involved in your machine: 

Catapults are full of physics. From the power that the catapult has, to the distant it can force an object to travel. Our Catapult also includes elastic tension to create its power. Potential Energy is also involved due to the position of the hand. This potential energy is not due to gravity though, it is due to the elastic force. Most of the power and energy of a catapult is made from tension. Catapult physics is basically the use of stored energy to hurl a projectile.

Design and Building Process: 

Day 1: At first we thought we were gonna make a cannon. So the first couple of days was full of drawing the machine, and making of list of supplies.

Day 2-4: After finding the design and supplies we spent a day making the cannon, these supplies included beer cans, gun powder (made of matches), and a wood platform. When finished we tested the cannon and came to the conclusion that it would not be appropriate to bring to school. The results were too powerful.

Day 5-6: After changing our Invention from the cannon to the catapult, we had lots of work to do! This included: making design, getting materials, finding the history of the catapult, and explaining the physics behind the catapult. Not gonna lie, we did a lot of procrastinating.

Step 1:

Step 2:

Step 3:

Step 4: Final Product

Challenges:

Along the way we faced many challenges. Our first challenge was losing a valued partner due to differences, that could of been dealt with a lot better. The second challenge we faced, was having to change our project entirely due to the overwhelming power of the cannon. Lastly, when making the catapult we had blown a fuse in the garage. Overall this was a fun project, but I would definitely do it different next time.

3 Reasons why

3 Reasons why I would not want to be stuck on this island:

This past month I have been reading the Lord of the Flies written by William Golding. I have came to the conclusion that being on the island would be a complete disaster and WOULD NOT BE FUN. Here’s why.

 

1. Everyone Would Smell

Imagine being on an island with multiple teenage boys. Not only are they teenage boys, they also haven’t showered for months. Months of sweating, eating, hunting, and playing the dirt, without showering. Sounds fun to me…Not. My mom won’t even allow me to eat dinner after practice until I shower.

 

 

2.  It would be a full time babysitting job!

The island not only has a bunch of stinky boys, it is also filled with little kids know as litluns. Could you babysit little kids everyday at the age of 12? I couldn’t. You would have to feed them, watch them, and put them to sleep, all while trying to take care of yourself and survive. If you lose Major props to Ralph for trying to taking care of all the little things while also trying to maintain order, as a kid!

 

3. There would no girls

Not only would being with a bunch teenage boys suck, there would also be no girls. Can you imagine trying to stay civilized while having no women to control you? I can’t. Not only would the island be less fun, there would also be no chance to repopulate and start civilization on the island. Which means life on the island would be a one way road to death.

Trigonometry

In this section I learned about trigonometry and this included SOH CAH TOA

SOH  CAH TOA helped me when it came to finding each side of a right triangle

for example if the triangle gives you the hypotenuse and opposite then u should use the sin this is why it is SOH

And you use cos when u have the Adjacent and  hypotenuse

Measurements 2nd half

This week I learned the difference between the metric and imperial systems and how to convert them;

  • the imperial system is the american system which includes miles, feet, inches, and yards
  • The metric system which most of the world uses, includes kilometers, meters, and cm

I also learned how to find the surface area and volume of prisms and cylinders;

Volume of prism= the area of the base of prism x height

Surface area of prism= add the areas of all the surfaces together

area of base= 2(pi)r
