Dog Whistles

The other day my younger brother was using a new dog whistle app on his phone to make tour dog (and me!) go crazy. However, my dad was in the same room and he couldn’t hear the annoying high-pitched sound at all, so my brother was able to get away with continuing the high-frequency dog whistle sound. The highest frequency dogs can hear is 45 kHz, while a child’s limit is 20kHz, and a middle-aged adult’s is 15kHz. Dog whistles range from about 20 to 54 kHz, so it makes sense that I was able

Do billiard balls hurt?

Put simply, the answer to this question is yes. But here's how I found out: The other day, I was playing pool in my basement with my brother and, of course, I was looking at something on my phone just as the cue ball was hitting the 9-ball and he applied so much force that the 9-ball bounced off the table and landed right on my foot. It hurt really bad and I still have a large bruise right on the top of my foot. Well, since a standard billiard table is .762m and we can use acceleration

Christmas Physics

Even though it is well past Christmas, I figured why not use physics to try to prove a myth that many kids believe, the myth of Santa and his reindeer. While Santa is said to have magical abilities that allow him to deliver presents in one night all over the world, let’s pretend that Santa doesn’t have magic and he just obeys the laws of physics. So, Santa has to visit around 500 million houses in the span of 31 hours (taking into consideration different time zones and the rotation of the E

All About Me

Other than being a student at IHS, most of my free time is consumed by playing volleyball. I also make time somewhere in my busy day to do homework and sleep. I don't know where I want to go to college yet, however I am planning on a major involving cybersecurity/digital forensics and I'm also interested in engineering, which is one of the reasons why I decided to take AP Physics C this year. I also wanted to take physics again because I like both science and math and this class involves both of

Air Resistance Tests

Last night my younger brother was watching one of his favorite shows: street science. I happened to walk in the room as they were doing a Galileo-inspired experiment where they were dropping different objects from a crane to show the effects of gravity and air resistance. At first, they dropped a basketball and a bowling ball from a height of 50 feet. Physics tells us that both objects should hit the ground at the same time because in free fall the weight of the object doesn’t matter. Howev
