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 V_{o. It stands for original velocity. When an object is simply just being released, not thrown its}  V_o is equal to zero because it is starting from rest. When an object is thrown down it's  V_o then contains a value because it has a certain speed. The bullet about to be shot by this gun would have a  V_o 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.
