Laws That Can't Be Broken



Hey guys! Welcome to rules that can't be broken! Remember how I told you that we were going to talk about Newton?  You don't remember who he is? Well if you must have a picture.... 

 

 

See? The over-achiever is back! This time he created three rules, or laws, that can't be broken. If you read my blog on Newton, then you'll remember that he created three laws of motion. Let's take this step by step shall we?

Rule #1: Every object persists in its state of rest or uniform motion in a straight line unless it's compelled to change that state by forces impressed on it. So basically nothing is gonna move unless you push or pull it. And nothing is gonna stop moving unless you push or pull it. You want examples? Since you asked so nicely!   =)

Let's use your phone for example. If I hold it up in the air, it isn't gonna move until I drop it (or push it down, whichever you prefer). Now that phone is gonna stay where it is until you push or pull it. Got it? Good. 

Rule #2: Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration. In simpler terms, kicking a basketball and a bowling ball with the same force is gonna hurt. Besides it hurting, the basketball will go farther. Why? Because it is lighter than said bowling ball. Now if I push the bowling all with more force, it will move just as far because there was more force. And the rest is just the formula F=m*a.

Rule #3:  For every action, there is an equal and opposite re-action. So again to put it simpler terms, for every force there is a reaction that is same in size, but opposite in direction. An example would be doing a belly flop in a pool. When you jump, you land in the water, it makes a splash. Let's just say the bigger you are, the bigger the splash. Now, here's a hilarious picture. Not really. But kinda. And something really cool below. Both show the third law. Role the pics!

 

 

 

 

Thanks for looking at my extremely short blog post. I know there wasn't a lot but still remember....

 

 

 

So all of my information came from here. All the pictures are just a Ctrl +Click away! Thanks for viewing! xx -G

I Will Try Defying Gravity!

None of you undrstand my title do you? Seriously? You don't even have to understand the musical but the song has been on Glee so many times... wow. Ok then. Rude. For the vass majority of you who don't know, Defying Gravity is a song from the broadway musical 'Wicked'. Love it so much! For those of you who used context clues, yes we are talking about gravity! So let's dive in. Wait! Safety first.

 

 

 

Ok now that every one is safe let's explore gravity! Now what exactly IS gravity? I'm glad I pretended you asked! Gravity is a force pulling on all objects in the universe. I'm serious guys. Everything. As in the Earth, a dog, a tree, the moon, the Sun, and even you. Before you complain in my comments, no I did not just call you fat. Again, I'm accepting of all people shapes and sizes.   =)



For example, is I drop a teddy bear off the roof of my house then it's gonna fall. Although it would be pretty awesome if it floated. Seriously a floating teddy bear, just think about that. So I trust you all remember Newton. No? You need a picture you say? Well sure. ^..^

 

 

 

Now do you remember them now? Just so you know I'm going to be using this a lot. If you read my blog post about him, then you remember me saying he had a miracle year. Well during said year an apple fell on his head and somehow he said "Wow this has to have something to do with how the planets work! OMG I have to write this down!" or something like that. Well that apple was being pulled by gravity and his gigantic head was in the way from it falling to the ground.

 

 

So another man had a giant influence on gravity is Galileo. Odds are you've heard his name but haven't ever seen his face so here ya go.

 

 

 

 

 

Catch ain't he? I don't know about you but to me, he looks very angry. I would be too, granted, if I worked ridiculously hard in science and all I get is my name featured in the Bohemian Rhapsody by Queen. Not that it isn't an awesome song... just sayin', give credit where credit is due.

 

 

So how exactly did Galileo Galilei (go on say it several times 'til it gets old, you know you want to) contribute to gravity and discoveries and all that jazz? Well there was once a philosopher named Aristotle and he thought heavier objects fell faster than lighter objects. Ol' Gal here decided to prove him wrong and everyone knows how great things go when you try to prove someone wrong in science. Basically this dude goes to the top of the Leaning Tower of Pisa with items of different sizes. Then he drops said items at the time and the same height. He then find out that he was right and Aristotle was wrong. You go Galileo! (Mean Girls reference there)

 

Wanna know something cool and slightly creepy? On the exact same day that Galileo died, Newton was born. My mind = Blown.

 

And just when you thought Newton was done being an over-achiever, he goes and contributes to gravity. Newton decided that gravity depends on two thing, mass (the amount of space an object takes up) and distance (that should be self-explanatory). The bigger the object, the stronger the gravitational pull. The farther away the object the weaker the pull.

 

 

Ok so let's go back to that whole fat concept.

 

 

 

In all seriousness, you aren't fat because I hate you, you probably aren't fat at all. But if you think you are you should blame gravity. Why you ask? Because weight is actually the percentage of you that gravity is pulling on. There is a giant difference between weight and mass. See, if there is a tiny ball of steel and a large teddy bear, the ball of steel has more weight, but the teddy bear has more mass. So no you aren't fat because I hate you (which I don't) you're fat (or skinny) because GRAVITY hates you.

 

 

 

 

 

Gravity is very important in multiple ways. It may have kept George Clooney alive.... comment if you go that. But in all seriousness again, it is very important. It kinda lets us STAY on Earth, and I don't know about you, but I like the whole staying alive thing. So wherever you are remember

 

 

 

 

 

I hope you guys had a wonderful weekend! Mine was pretty awesome and interesting. I witnessed a 13 year old boy being mobbed at North Point. That was funny. It also made me lose all faith in humanity. But more funny. Anywho, all my info is from here. All the picture either have hyper links or they're just a CTRL + Click away. Hope you learned something from me! I'm just gonna pretend that I'm not bothered by the fact that Newton has more voluminous hair than I do. Bye until next week! xx-G

 



Star Wars and Band References!

There are going to be a lot of puns in this one, so hold onto your hats! Or I guess the most socially acceptable head wear are beanies and snapbacks, so hold onto those! This time we will be discussing force. If you read my last blog post, you'll know that I'm about to make lots of puns. Shh... Just Go With It. Yes that is an Every Avenue album. Look it up, they're a good band.   =)
I have to give you a little background review so...

No we are not talking about the Skywalkers' use of the force (although Luke is pretty adorable), we are talking about the scientific, REAL force. The one in REAL life. Did I mention this one is REAL? Ok good. Back to force.

Force is the push or pulling of an object. To be more fancy, force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or shape. Basically, anything that causes change to happen. Get it? Got it? Good.

Moving on. Ok so I thought I wasn't going to be able to reference Teen Wolf, but I guess I can. Knowing some people will skip this paragraph, I'm not going to include pictures of the Carver twins that I'm going to be using. Let's say Aiden and Ethan combine to make that giant Alpha werewolf thing. Now Derek is an omega, so he's tiny and weak. The twins can grab him and fling his across the room, and Derek can't do anything about it. That, my friends, is an example of something influencing Derek's movement and position, therefore it is force.

Now for those of you who skipped the paragraph up there ^^^, I have a picture for you.

See this number 1 dude? Ok well he was holding a rubber, yellow ball. He was bored and saw a squirrel. Since he was bored and wasn't thinking clearly, he threw the ball at said squirrel, injuring it greatly and making it very, very angry. He changed the position of the ball, therefore he applied force. Next and final example. Hopefully, you had/have a wonderful childhood, and you played with Play-Doh at one point in your life. Now let's say you make a ball and flatten it. You applied force by trying to make an inedible pancake. Good Job!

What exactly do you measure this with Gabby? I'm glad you asked random internet person! Now you remember when I showed these two dashing fellows in a previous blog post?

Ok I will openly admit that I chose the comparison because let's face it, Lahey is adorable.

Anywho, Newton is going to come up a lot in the next few blog post so beware. Force is measured in Newtons. But what are Newtons? Newtons are the units used to measure force. The formula involves multiplication (shocker considering all of the other formulas we've done involves a / b = c), so put your thinking caps on. The formula is F=ma.

 

Knowing the people who are going to be viewing this are most likely in my class and are laughing at this, I chose a picture that was both educational and slightly funny!

Okay so I haven't told you everything yet. Actually, I'm no where close to being finished so get comfortable m'kay? About net force next, we must talk. (Yoda reference, don't laugh I'm a geek at heart okay?)

Net force net force..... How to explain net force. Maybe this picture will help, yeah?

Doesn't help? Ok well... umm... let me see how I can help. See, net force is the overall force acting on an object. Gravity, believe it or not, is not the only force acting on us. If it was, then we would go right through the Earth and that would terribly and horribly painful. But the resistance force and gravity have to be balanced or else one would win and we would either float or sink. That's a song by Fall Out Boy by the way. Look it up on YouTube, too. 

Balanced forces are forces that have the same acceleration and the cancel out. The result? You don't move. Unbalanced forces are one having more (here's that word again>>>) Newtons than the other and that result is you moving. 

Okay stay with me because we're almost done here. Last thing we have to talk about is thrust.  Yes, you read it correctly, thrust. Thrust is a reaction force that results when accelerating mass goes in ONE DIRECTION (bwhahahaha =P). Want examples? Look at the picture of net force and the one below ^ ~ ^

 

Okay that was a very long blog post wasn't it? Dear lord. One final note, nothing big or anything.  Just a little fun fact; Centripetal force! What is it? It's a force that makes something follow a curved path. Like in the superhero movies like Batman where he uses that grappling hook and shoots it at a giant steel pillar thingy and it turns his car in a complete circle to make a U-turn. There is totally science in superhero movies. Cool huh?

So I hope you liked my blog! There was a lot of information on this one, so sorry if you thought it was really lengthy. That and I'm a rambler so it may have been random stuff. Any who, links to info are here and here! Links for the pictures are the same as usual, CTRL + Click. Have an awesome week and I'll see you next time!
