Week of 11/2-11/4

This week was another short week it was three days. We focused on one main topic which was velocity and also we learned formulas to calucate position. Even though this week was only 3 days it was very diffulct for me to follow along. We learned about that Velocity can also mean speed. We used a formula to find position and the formula is x(t) *time=position. For a problem that gives a graph using that formula you can determine the position of the dot at a certain time.

We also had to complete a lab on how far a battery powered car goes each second. The first car we tested had both its batterys in. My team layed down a ruler to determine how far the car went in each second. Another one of my groupmates looked at the clock to say mark at each second. For the first second it travelled 13 and a half inches, then in the second second it made it to the 25 inch mark and lastly for the 3rd second it hit 36 inches. From the first second to the second it traveled 11 and 1 half inches. Then, for the second mark to the third it travelled 11 inches. So the two numbers it travelled in a second it travelled about 11 and one forth inches. Then, to test the car to make it slower instead of putting the two batterys in. We put one battery in and a medel rod. Which made the car run but with only one battery. The car of course went slower then the first car because it only had on battery. We did the same thing we did with the first car. And these are the results. For the first second it travelled 9 inches and for the second second it travelled 14 inches and lastly it went 20 inches. The car travelled 5 inches inbetween the first and second markings. For the inches inbetween the second and third markings its 6 inches. It was a big difference compared to the faster cars intervals in inches. With more battery power or even energy in general it will be more efficient and be more worth while.

The car experiment we did this week I understood it very much but for the formula and graphing I didn't understand it to much. The real world applications for the car experiment is if you have a real car and its filled to the top in gas it will surely drive faster and longer than a car with 1 quart of gasoline.
