This picture I took shows many example of kinematics. I took this at the UH Volleyball game this past Friday when they played University of San Francisco. I took this picture of one play in the game, where UH won the point. Each volleyball player who hits the ball in this play displays kinematics. For one, that volleyball is going many meters per second, but I’m not too sure how fast…it’s just fast. Velocity is defined by how fast something is going and in which direction, and this play can show that the volleyball is going fast in the direction towards their opponent’s net. After researching how fast volleyballs usually travel, the average is about 70mph for the professional players (when they serve the ball), so that means the volleyball in this picture was traveling at a speed of about 31 meters per second if you convert it into the SI unit for speed.

Unit of Measurement
As you can tell, the picture that I took was of a 12-inch ruler. I chose to take a picture of this because it's one of the many tools that are useful in our everyday lives. Rulers can measure inches, centimeters and even millimeters. This relates to our unit that we’re working on because it since the unit has to do with measurement and different types of units; a ruler fulfills both of these requirements. This relates to the experiment we just did because instead of using a meter stick, we could have used a ruler to do our measurements since 1 meter equals about 3.2 feet. It just would’ve taken a lot longer.

Blogpost #1
My name is Rachelle and one of my favorite things to do is spend time with family and friends. It may sound cliché, but whether it’s going to the mall, movies or beach I always have a great time with them. So far in science I have taken biology and chemistry and my average would probably be a B. I think that’s good for me considering science is definitely not my strong subject. This year I am taking Honors Algebra 2 and hopefully it’ll help me with calculations in Physics. In completing this course, I hope to look back on it and say that I learned a lot and I had fun at the same time. I think Physics is the most interesting out of the three main science courses just because it deals with everyday life. In my picture I’m with my dog that we just recently had to give away. I think this photo represents my belief that you shouldn’t take anything for granted because you never know when it won’t be yours anymore. It goes to show that what you have may not always be yours so you should make the best of what you have when you have it. (:
