In physics we assume that gravity is a constant. In fact we represent this constant with the letter g and the numerical value of 9.81m/s2. Almost everything we learned this year works on the assumption that gravity is constant on the surface of the earth. There is no reason to assume other-wise after all we don't just see objects floating randomly as we take a stroll down the street. We use physics and its assumption of constant gravity- on the earth's surface- to create a lot of our technology
Some of you may be familiar with Lupe Fiasco's song Kick Push. This song is basically about a skater boy who meets a skater girl and skate off into the sunset. Now I don't know a lot a bout skateboarding but I know a little bit about the physics behind it.
Let start with part of the first verse:
First got it when he was six didn't know any tricks
Matter fact first time he got on it he slipped
Landed on his hip and busted his lip
For a week he had to talk with a lisp like thissss
How was the universe created? Well as long as your guess isn't the Big Bang Theory your theory might be valid. The truth is that we have no idea what so ever how the universe was created. Some people believe in creationism- that the universe was created by a higher power. Those misinformed in the subject of Physics often believe in the believe in the Big Bang Theory. I however have always enjoyed the theory posed in the movie Men in Black. For those unfamiliar with this franchise it's basically
Siren are by far my favorite mythological creature. In traditional Greek mythology they are bird like creatures which live on an island. Their 'siren songs' cause sailors to become entranced and steer the boat towards the island whereupon they crash and became shipwrecked. In some myths the sailors would starve to death. In other myths they just simply drowned. According to other myths some sirens actually swooped up the drowning sailors dropped them onto the sharp rocks of the island and then f
In the modern world file sharing is becoming more and more popular. For those who aren't familiar with the term file sharing it's the illegal downloading of music, movies, t.v. shows and other media blocked by copyright laws. Sometimes the quality of 'bootleg' movies and t.v. shows are pretty good. Other times the quality is just pitiful. Ever watch a movie where the sound doesn't match up with the movie? well you can blame physics for that one.
When we watch a movie we are simultaneously pr
One of the episodes of the cartoon Teen Titans go is called Power Moves. In this episode the titans combine their powers to create new moves. The purpose of this is to make their attack more powerful. In physics we learned that power is the work done over time. P= w/t In order to determined power we must also know what work is. Work is defined as the process of moving and object by applying a force. it is measured by the equation W= F x d
One of the first power moves preformed is by Beast Boy
Although it is said Isaac Newton didn't really get hit in the head with an apple let's suppose he did. When people talk about this scenario they usually talk about , why that apple fell out of the tree. let's instead look at why all the other apples didn't fall as well.
An apple has a mass of about .18kg And the branch which holds the apple up acts as a tension. When the apple is hanging there it is in static equilibrium. This means when you add up all the net forces the equal zero. As a resu
A bunch of my friends and I are going paintballing after midterms for the first time. Paintballing is like a physics teacher's dream and possibly a physic student 's nightmare. Paintballing is basically all about projectiles. A projectile is an object that is acted upon by only gravity. This describes the paintball after it has left the paintball gun. Now I want to walk away from this outing with as few as bruises as possible. I want to figure out how far away I have to be from my friends in ord
Turn your head for a second and the world of babysitting quickly turns in a world of collisions.
A collision is defined ad an event where two or more objects approach and interact strongly for a brief second. And well, my little brother and sister have a tendency to run into each other. A lot. Most of the time this results in a elastic collision otherwise known as a bouncy collision. In this type of collusion my brother and sister run into each other and then bounce apart. In this collision k
Homemade Yankies is a common holiday dish served in my family. Everyone in my family, from a young age, learns how to make this homemade pasta in sauce (with the option of homemade meatballs if you aren't vegetarian like me) The pasta has to be rolled into long strands where it's cut, boiled and then cooked in red sauce. However as a child and even now, I always hated rolling the dough because once I got to the end my hands would turn red and itch unbearably with heat. Later on I learned that th
Dog mushing is better know as dog race sledding and if you've seen snow dogs you know what i'm talking about if not......... I have no words for you..... but as quick summary it is a team of dogs( trained Eskimo dogs,
Siberian Huskies<3 Samoyeds or Alaskan Malamutes) who pull a sled controlled by a 'musher'. And of course dog mushing = physics. The main connections are through velocity, acceleration, friction and force.
On the sled at rest there is friction, and gravity pulling the sled
Hula hooping was a big part my childhood, I mean I literally had a gym unit on hula hooping in grade school. But ever wonder how it works? Well the answer is Physics.... big shocker there. The spinning of a Hula Hoop around a person's hips can be attributed to several forces (1) you as an upward force (2)gravity as a downward force (3)torque as a spinning force) and (3) friction which acts in opposition to torque..... The person moving their hips inside the hula hoop is exerting an upward force
Halloween should really be a celebration of physics. I mean you couldn't ring the doorbell without pushing it and this action right here my friends is called a force. And when the person opens their door they too are applying a force. Their door would choose to stay at rest but because it was acted upon by a net force- the person pushing it open- it opens instead. Now let's get to the most important part: the candy. When the person drops candy into your bag, the candy is in free fall. You can ev
Ever read a book? Well let me rephrase that for some people.... ever read a couple pages out of a book pretendding to read the whole thing for english class? Well guess what my friend, not only have you practiced Physics, but you demoonstrated Newton's 1st Law of Motion as well!!! When you open the cover you are applying a force onto the book's cover. A force is defined as a push or pull on an object. Hence, when you pull open the cover and then push it down you are applying a force to it. When
Physics is everywhere. Even in the sewers of NYC, in the world of Teenage Mutant Ninja Turtles. Whether fighting villans such as Shredder or training under Master Splinter these turtles demonstrate a kickbut use of physics. For example, while Michelangelo is fighthing, he loses his balance and falls off of on a building. Now lets supposse this building is 142 meters high (the average height of NYC buildings) .And on t.v. it takes five seconds for him to fall. We can callculate the average speed
