Projectile Motion

I was playing tennis with my dad and remembered I had to do a blog on projectile motion. Projectile motion is again when an object is thrown or shot or bounced or put in the air and it moves along a curved path like a parabola. That path of motion is called the trajectory. Depending on how far and how fast something is moving in the air will determine how curved the line is. When you serve a tennis ball it goes in a parabola motion. It goes fairly straight motion because it is moving quickly but it is still moving like a parabola. All projectiles we are using are only being calculated with the affect of gravity.

Projectiles

I was playing tennis with my dad and remembered I had to do a blog on projectile motion. So I took the tennis ball and took a picture of it because I couldn’t take a picture of it in the air moving while I was playing. Projectile motion is again when an object is thrown or shot or bounced or put in the air and it moves along a curved path like a parabola. That path of motion is called the trajectory. Depending on how far and how fast something is moving in the air will determine how curved the line is. The line that a tennis ball follows when it is served is most of the time more of a flatter curve because it is hit hard and as straight of a line as possible. When you look at the velocity vs. time graph of the tennis ball moving it should be moving relatively constantly.

Quarter 1 reflection

This quarter in physics was quit an eye opener. I was confused in the beginning of the quarter with all of the new equations and rules that we had to memorize and follow all the time. It really helped that we had acronyms for the equations that we used. Over this quarter I learned a lot about the difference between accuracy and precision. We also learned 4 major equations. Our equations used distance, average velocity, time, acceleration, total velocity, and total time. We used the acronyms (dat) for equations using distance, acceleration and time, (vat) for equations using velocity, acceleration and time, (vad) for equations using velocity, acceleration and distance, and we also used the acronym (dvt) for equations using distance, velocity and time. All of the acronyms help us identify equations quicker. One thing that we learned that I found that helped me with all of the questions that we did was stating the givens and also drawing a picture.  Both of those techniques help me further understand the question. Some of the questions that seemed very easy were even easier when I made a drawing and stated the givens. We have a board called “The Equation Board not bored” which contained all of the different equations that we have to memorize.

Myself

My name is Kainalu Asam and I was born in Washington. I love running, surfing and skating. I attend Kamehameha Schools Kapalama Campus. Freshman year I took Biology and I enjoyed that course and I understood it pretty well. Sophomore year I took Chemistry. That course was very confusing to me with memorizing the different formulas and the different powers of different elements. This year I am taking physics. So far this course is fairly understandable. It is getting a lot easier as time goes on and I get more practice with everything that we have to learn. I am currently in Algebra 2b and I am taking college algebra next semester. Completing this course will give me a better understanding about the world around us. I chose this picture because cross country is what my world is revolving around right now. I wish that i could be surfing but there is just something about this sport that makes me want to do it time and time again. It could be the reward of winning state championships or just the thrill of the sport but the pain that we go through just makes us stronger.

Acceleration

The topic for this blog is acceleration. Acceleration is the rate of change of velocity per time. And velocity is the speed of something in a given direction. Acceleration was a difficult topic to find but when I was walking around my house I found my faucet. When you first turn the faucet on the velocity increases very quickly which means that it is accelerating. When you stop increasing the power of the water, the acceleration goes to zero. When you slow the water power down it decreases in acceleration. Once you find the right water pressure the water has a constant velocity but because it is not increasing so the acceleration is zero. Acceleration is difficult to find outside of class but it was a very educational thing that made me think a lot.
