Blog Post #10

Hey it's me again with yet another blog post on force.  Today I am going to talk to you specifically on Newton's 1st law.  This law states that an object in motion tends to stay in motion unless acted upon by an outside unbalanced force.  This basically means that if an object is in motion, taking my picture of a cross country runner as an example, and say he is running at a constant velocity, the moment he crosses the finish line, he will be acted upon by an opposing force.  Meaning he will stop.  However, he is not only stopping, but he is decelerating or accelerating in the opposite direction.  Because if he were to stop suddenly, he would most likely fall over or trip.  I believe this is due to momentum or something (we didn't learn that yet).  But anyways I believe that is what you need to know about Newton's 1st law.  Next week I will be hopefully going over Newton's 2nd law.  

Blog Post #9

Hey there I am not sure if I used this pic yet because this pic was taken back from a month ago.  Anyways I will be talking to you about force today again.  I am going to talk about "freebody diagrams" (without the diagram).  So as you can see this is a picture of a runner.  You may not know this but this was taken at the finish line.  So he is decelerating.  Free body diagrams measure anything that force pushes or pulls against.  So there are two forces that we are able to find.  That would be the mass of his body pushing down and the force of the ground pushing up.  This causes the body to stay up right and not fall over.  Now, because he is decelerating, he is accelerating in the opposite direction, or backwards.  So when drawing the diagram we will have an arrow pointing down labeled "mg" and an arrow pointing up labeled "N" for normal.  Both of which are the same length.  Also there will be an arrow pointing opposite the runner's direction.  So if we was running to the left, the arrow would be pointing to the right.  And vise versa.  Also this arrow should be labeled "F for force".  And that is basically it.  So I hope you have enjoyed yourself.

Blog Post #8

Hello fellow bloggers.  I am back with a new segment of my blog.  Today's focus is on force.  So, this video is of my baby cousin pushing his baby walker.  The definition of force is simply a push or a pull.  More specifically we are going to focus on contact forces today.  Contact forces are caused by contact of contrasting 2 objects.  Basically this means that the baby walker is one object and my baby cousin is the second.  When my cousin pushes against the walker, it causes a contrasting force, making the walker move.  And that is what a contact force is.  There is another force that I didn't cover.  This is called "at a distance force", which is forces that are not touching.  This could be like an object falling.  There is nothing pushing it, however, gravity is acting upon it, making it move.  But I won't get too much into detail about that.  So thats it for this week. I hope you learned something and that you had an idea of what a contact force is.

Extra Credit Blog Post #1

Hey so my teacher Mr. BUREKU (ブレク its actually an english name but for privacy purposes I spelt it in Japanese plus it was something that we learned in 2D kinematics) told us that this was an extra credit blog post.  We had to make sure that our parents have seen our blog.  But he wouldn't believe us if we were to get a note from our parents because anyone could forge it.  So I decided to make a video of my mother at home reading my blog, while simultaneously cooking dinner.  And of all the blog posts, she had to read the one that I turned in late.  Go figure.  Anyways, you can watch the video, I think you will laugh at the background noises and the fact that she was unable to keep a straight face when speaking.  So enjoy, and I hope I get extra credit.
P.S. I didn't exactly know if i were to write a hundred words so I did anyways.

Blog Post #7

Hey sorry this is late.  Anyways, today I will talk to you again about vectors.  So this weeks focus was on displacement vectors.  Displacement is basically the distance from the starting point to the endpoint of the distance traveled.  This picture was taken this Saturday at the cross country meet at CORP.  The runners were to run a set course going west for a certain distance, then northwest for a certain distance and end somewhere around the south for a certain distance.  We can use displacement by starting from the starting point and measuring the distance traveled to the endpoint.  So that was basically displacement in  a nutshell.  Hopefully I will remember to make a blog post on Sunday this week.
