Force by Penubag

Summary:

       Force can simply be defined as a push or pull. Force is energy that results from a movement. Force also has a unique relationship with vector quantities as is it is a vector quantity, but it is also the thing that creates vector quantities. This is because a vector quantity is created by a force that has magnitude and direction. Due to how force and motion are directly correlated, force has much to do with motion. The first of the three laws of motion (according to Isaac Newton) is that objects in motion tend to say in motion. At the same token, objects at rest tend to stay at rest (this is also known as the law of inertia). The second law is, "the acceleration of an object as produced by a net force is directly proportional  to the magnitude of the net force (how big the force is), in the same direction, as the net force, and inversely proportional to the mass of the object (how heavy the object is)." In other words, force is equal to mass multiplied by acceleration. The third and final law is that for every action, there is an equal and opposite reaction.

S&EP 5-Using Mathematics and Computational Thinking:

       I used mathematics and computational thinking when answering questions about force. These types of questions were questions that mainly involved net force. I had to use mathematical thinking to add, subtract, and predict. I used mathematics to add when two forces were acting on an object in the same direction. I used mathematics to subtract when two or more forces were acting on the same object in opposite directions. I then had to subtract the smaller force from the greater force to find the net force (the difference of the equation). Lastly, I used mathematics to predict when  being asked questions such as, which side do you think will win the tug of war. I had to take into account the combined mass and force of both sides to try and find the most promising winner. This is how I used mathematics and computational thinking.

XCC-Energy and Matter:

       One thing that I realized this week was that energy and matter play a massive role in the system of force. This is due to how both energy and matter are needed to make force work and exist. This is because of how energy affects force and force affects matter. As energy is needed to actually produce force. In result of this created force, matter is being affected by the force pushing or pulling the matter. For example, if a human scores a goal in a soccer game, he used energy to swing his leg at the ball. This energy created a force that affected the ball (which is matter) which caused the ball to be pushed and move in such a way that it made into the soccer net so that the human could score a goal. This is how energy and matter work in the system of force.

Systems In a Human Body Info Paper 10/15/15

Friday and Monday we were writing down the definitions of (I believe) organelles that are part of the urinary and digestive system. Here are some examples of some of the organs my class had to write down the definitions for, the esophagus, the pancreas, the liver, the small intestine, and the large intestine. One thing that I forgot to add is that there was one other paper that had the definitions down for my class because I did not want anybody thinking that my teacher would make us write the definitions on our own out of the blue. The way we knew the definitions was because on Thursday or Friday I forgot which day any ways my teacher showed what every organ that we had to write the definition for what each organ did in order. But the fun part was she assigned every single person in my science class an organ to make it fun. What also helped was that Ms. J went over the answers with my science class also she allowed us to switch our answers if we got them wrong that especially helped

Chemistry Mastery Quest 2 Regrade

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

Plate Tectonics 3/10/18

Image
Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges with a lighter con
