Quarter 2 Blogpost #7

I was relieved when our egg survived for what seemed to be a forever drop.  When making this device Joe and I were planning for no wind and for our cone to crumple and increase the time of impact.  Instead it landed on the circular top which absorbed most of the momentum.  Inside we cushened the egg with packing foam just to increase the impact time for when the egg would hit the side of the container that it was in.  The only one flaw that our design had was if the wind blew the device so that the circular top landed first.  If that did happen our egg would break because the impact time would be much shorter.

This week I really hope that my groups egg will survive the three story drop.  I was planning on using cornstarch and water in a plastic bag as some sort of crushing for the egg to lang on.  This lab plays along great with what we are learning because if we can find a way to increase the contact time of our object hitting the ground less force will be put on our object.  I think that also need to study the 3 dimensional explosions that we had on the P.A.  Over all I think that this week was a major one because we are learning a lot of important major concepts.

Now that we are on the unit of momentum I am able to understand why things keep moving at the velocities that they travel.  This past lab also helped my understand visually on how momentum is neither created nor destroyed.  The lab also helped my see how and in what direction momentum was transferred when two carts collided.  I was also able to see how objects with different masses affect the amount of momentum an object has.  Over all this week I was able to understand some key concepts that will hopefully help me on this upcoming unit exam.

Momentum
To me momentum is the physics of why things move the way they do.  I think that inertia has a big role in an objects momentum.  There must be a direct relationship between the two.  The more inertia an object has the greater its momentum will be.  This sounds a little confusing at first because we had just learned that when two objects collide no matter what the mass they both put the same amount of force on each other.  I looked up the formula for momentum and this is what I found: p=m*v (p= momentum, m=mass, and v= velocity).

2nd Quarter Blog Post #3

This week we are still on the same subject of finding out the newtons of different problems.  We are also learning about how tension works and how all of the different axis operate independently.  I learn better when Mr. Blake makes the learning fun by making up inovative terms such as "da whole ting."  I am still having trouble on learning how all of the axises work independently and where to plug all of the variable in to the equation.  

Blog Post #2 for quarter 2

This week while learning about Newtons I found it hard to solve the three vector problems.  On the previous PA I was able to grasp the concept of Fnet=ma.  Over the course of the week I understand a lot more about why things move the way they do.  Newtons laws of physics are true, even for humans most of the time.  Along with the labs I find it easy to grasp all of the key concepts that Mr. Blake is trying to teach.  I am glad that there is only one set of equations so far because it limits my chances of error on the upcoming exam.

Blog Post #1 (2nd Quarter)

With the start of a new quarter we now are learning about force and why things work the way they do.  We also are learning the Newtons laws and theries.  The labs that we are about to do seems interesting because it contradicts Newtons law that states "objects at rest will tend to stay at rest unless acted upon by an outside force." Since we saw you move the paper but yet the pen stayed in the same place that it was, only now that the pen is on the desk.  I asume that the paper is moving faster than friction is able to hold the pen in place.
