What I Learned In Physics, First Semester...

This first semester, I learned many things in Physics. I learned about Kinematics, which is the science of movement. We did a fun pendulum lab, and I also learned that spam musubi’s are kicked and thrown very often, in the name of science. I also learned about momentum and collisions, which was fun because we got to crash cars together on a track. We also found out that using water balloons in Physics is actually quite fun. We heard the story of the rebels who fired their cannon straight up into the air while on a moving cart, and the tale of the amazon who was chased by the piranha people. Energy was quite fun to learn about also, as it gave me an idea as to how much actual “work” doing anything takes. I learned that a myriad of forces affects everything we do, even when still. There are also rules to how these forces work, and for every force, there is an opposing, opposite one. Also, Isaac Newton was a boss. He actually discovered amazing things about how our world works, so much so that his Laws are a large part of what Physics is based on. So, if Isaac Newton can do it, why can’t everyone? I think that the most important thing that Physics has taught me is that you can achieve anything…as long as you take into account the Force you are using, the friction of the surface you’re on, the acceleration of gravity, velocity, mass, yaddayadda….oh…and MASS IS NOT WEEEEIIIIGHT!!!! Thank you Physics!

Blog #13: Momentum/Impulse/Collisions

In this post, I'll be explaining more about momentum, and also about impulse and collisions. In the picture above, we can see why the car from last week was suddenly braking. It appears as though it and a brown car have had a collision. A collision is when two moving bodies exert forces upon each other for a relatively short amount of time. So when the two cars' momentum carries them towards each other, they eventually collide. Along with that, comes impulses. An impulse is anything that changes the momentum of an object, which in this picture is the other car.

Blog #12: The Definition of Momentum

Hey everyone, in this post, I'll be talking about the definition of momentum. Momentum can be defined as the quantity of motion of a moving object. This can be calculated by using the equation P=mv, where "m" is the mass of the object, and "v" is the velocity. The picture above is one that I drew to demonstrate momentum. In the picture, the car is braking suddenly, but continues forward because of momentum. And yes, thank you, it IS a masterpiece... :3

Blog #11: Forces 3

Back again. Today, I'm going to be posting once more about force. This is the last one, I promise, hehe... :3 Anyways, the picture above has my lanyard swinging like a pendulum. Because it is swinging, the forces acting upon it are unbalanced. Firstly, the force of gravity is attempting to pull the lanyard downwards, creating tension in the lanyard itself. This means that the mass will be gradually pulled towards the center of the swing-arc. Along with that, there is the force of wight that allows my lanyard to swing back and forth.

Blog #10: Forces Part 2

Hey, everyone. Once again, I'll be posting about forces. In this post, the picture included is one of a paper falling. The paper has many forces acting upon it, but the forces are imbalanced. This can be seen, because the paper is falling. What this means is that the force of gravity is larger than the normal force. Also the paper may fall slower than other objects, because of wind resistance also acting upon it.

Blog #9: Forces

Hello, everyone! It's been quite a whole since I posted, huh? Anyways, today I'm posting about forces. A Force is anything that causes an object to undergo a change in speed, direction, or shape. For example, the stapler in this picture is actually being acted upon by different forces. The reason it isn't moving everywhere is because the forces are balanced. One such force is weight, which can be seen by the equation Fnet=ma. Reacting against weight is the "normal force", which is always the same as weight. So, since the two forces are balanced, the stapler is at rest.
