Projectile


This week in physics class we learned about projectiles. The definition of a projectile is: something that has a single force affecting it, gravity. We conducted multiple experiments and used logger pro to analyze and understand projectiles. For example a person jumping from point A to point B would be considered a projectile because the only force affecting it, is gravity. The video above is an example of projectiles. That is my brother Byrne who is jumping from point A to point B. The only thing affecting him is gravity because there is nothing else putting force upon him. Projectiles are pretty cool and I am very excited to analyze other forms of projectiles.

Teach the Makua

This is a video of me teaching my father about some concepts learned in Physics this quarter. Enjoy!

Q1 Physics in a Nut Shell



Physics is all around us in everyday life. It is pretty much the fundamental building blocks of how things work and why it works that way. Through this course I was able to understand many parts of my everyday life. To begin, the first thing that I have learned is the difference between accuracy and precision. They are both very important in physics. Accuracy is how close a value is to the “accepted value” while precision is how repeatable the values are. Another thing we learned in physics was periods of a pendulum and how different factors affect them. After an experiment we had conducted we learned that only the length of a pendulum affects it period. When we finished learning about pendulums we moved on to the unit of movement and kinematics. In this unit we covered many different terms such as, velocity, displacement, acceleration, and many more. This whole unit was basically to learn and understand how things relate to each other and how movement is a very complex topic. We learned how to solve multiple different equations to find out certain information on movement. Like “d,a,t” equation. An equation used to find either distance, acceleration, or time from a moving object. Mr. Blake taught us these equations to help us further understand relationships in this broad topic of movement. Another thing we did pertaining to this whole unit was graphing. We learned how to graph movement and the parts of it. One thing we figured out is how graphs in movement can be converted and relate to one another in some way or another. Like a distance vs. time graph, it can be converted to a velocity vs. time graph using slope. This quarter I learned a lot about the world around me. Through this class I was able to further understand why certain things happen in this world.

Kinematics

This is a picture of a nerf gun. This nerf gun is a part of physics in everyday life. When solving certain equations in physics you use different values. One of the values is labeled as Vo. It stands for original velocity. When an object is simply just being released, not thrown its  Vo is equal to zero because it is starting from rest. When an object is thrown down it's  Vo then contains a value because it has a certain speed. The bullet about to be shot by this gun would have a  Vo with a value because it is being shot out with force. Meaning that there is movement from the very beginning. After the bullet from this gun hits the wall it will begin to decelerate. The bullet will begin to fall to the ground. The acceleration in which it would fall would be 9.8 m/ s. It would be this value because we are located on earth and that is what gravity is. It is amazing how things work in such weird ways. It is even more amazing how physics is literally all around us. Everything in life relates to physics. This simple nerf gun for example. It contains both velocity, original velocity, and even gravity. Before this class I would have never been aware of how truly amazing and alive physics is.

Acceleration

In class this week we learned about acceleration. Acceleration was defined as the change of speed. This is a picture of the inside of the car. On top of the thing behind the steering wheel there is a thing that shows acceleration. There are numbers and it shows the change of speed. Acceleration was something I did not really know about before this week. To me I thought it just meant to start moving. I mean that is technically true, but not really at the same time. I think it is amazing that cars are so amazing that they can calculate something like acceleration. Acceleration is something that seems complicated but it really isn't. It's simple all you have to do is break it into parts.

Displacement

This past week in class we learned about  motion. A sub topic within motion included this thing called velocity. Velocity is equal to displacement over time. We learned that if a race starts at a certain point and ends at the same point the velocity would be equal to zero because there was no distance that was displaced. This is a picture of my brothers getting ready to start a race. The start and finish point is the same. According to what we learned in class. The velocity of them during the race would equal zero because there was no displacement.

What is Motion?

Unit 2 in physics contains the concept of motion and what it is. In class we were not able to go into depth about what exactly motion was, but in this blog post I will discuss what I believe is motion. My definition of motion is when an object recedes or proceeds toward another object. Motion is also when something is able to move from point A to point B. Motion is a common thing, but seems impossible to define. How can such a common topic be so complicated? I am definitely looking forward to this unit and learning about what exactly is motion.
