i don't know one person who actually enjoys walking up the stairs. in fact, i hear people complain about having to climb 3 flights of stairs multiple times a day! yet why is it so miserable? well in order to lift yourself up one step, there needs to be a force of at least your weight in order to go up the step. when there is a large amount of steps, that's a lot of work that is done in order for you to walk up the steps. since work is being done because a force is causing a displacement, that al
At practice today, we were preparing for the next upcoming tournament (USA Disney Tournament) which is less than a month away. Our coach has us to a wide range of things at practice today, like she usually does. but there was one drill we spent a specifically long period of time doing. it was quite a simple drill, considering all of the girls there have been playing field hockey for years, but it had everything to do with momentum. Coach Tori had us roll the ball to a partner and we had to run u
During my junior year of high school, my 5th year playing field hockey, i made several connections with field hockey and physics, whether i wanted to or not. As center mid for my team, i am involved in almost every play, so i see in every way, shape and form how physics dictates the way the game is played. In our sectional game i had a beautiful aerial that went over everyone and straight into the circle where a teammate was and the play lead to a beautiful goal, which helped us with the game! L
In practice last week, our coach had us working in stations. One of those stations was lifting the ball and trying to hit the wall as high as we could. She had us start really close to the wall and focus on the fundamentals and then once we mastered getting the ball high in the air up close, to back our way up. What i realized when i got home was that we had just learned a bunch about the conservation of energy in objects, and how it is never created or destroyed. As soon as i did work on the ba
So for about 3 months now, i've been working at a small pizzeria in town and it came to my attention recently that at work, i don't really do any work. I may go and get peoples orders from the back, or answer phones, but i never move from my spot at the front counter without returning to it. So since there is no total displacement in my location for the shift that i work, i technically am not doing any work. Sure it takes energy to do the jobs that i have to, like deal with rude people on the ph
Throughout my field hockey season this year, me and several of my team mates had the joy of being at the wrong place at the wrong time when another team mate was hitting the ball. Most recently, during the semi finals, I got hit twice within the same half while blocking up a hit. Let's just say being 5 yards away while someone is driving a ball in your direction isn't always the most safe option. But today in class my teacher brought up Newton's third law, every force has an equal and opposite f
Ever since i got my permit I've been obsessed with driving everywhere, as lame as that sounds, it's true! Yet i know that i would not be able to drive if it wasn't for physics. One of the issues i have had is the remembering to take off the parking brake. I always forget when i start the car that i have to take brake off before the car will actually go anywhere. Since i always i forget this, the car is stationary (a constant velocity of zero) and the forces acting upon the car are equal, until i
about two and a half weeks ago, while everyone was still on the bath craze, I googled how to make my own bath bomb. I was home alone and had way too much time on my hands. so I found that if I put olive oil and cinnamon sticks in my bath that it was very good for my skin. so having nothing better to do with my time, I made the bath. well I forgot to clean out the tub after, and when my sister took a shower, she slipped right on her but. this is because the oil from the bath filled in all of the
This past weekend I had the benefit of being able to go to the Philadelphia area for a college trip with my aunt. What we decided to do while we were down there was take the train to NYC, since I had never been before. The trip took forever! Basically passenger trains from Philadelphia to NYC basically are like busses that go just a little bit faster. Anyways, what I noticed while we were riding was how much physics was really involved in train transportation. the way the train works is by runni
I was able to go to Universal Studios earlier this year and i couldn't help myself from visiting Harry Potter World. On top of the Gringotts (a bank in the books) was a huge dragon in which everyone once and a while would breathe fire and make a loud growling noise that usually pairs with fire breathing quite nicely. This was an extremely loud sound that no one in the park could miss. In order for the noise to be that loud, the sound waves produced needed to have an incredibly large amplitude wh
When my field hockey team got the opportunity to go to Disney for the huge national tournament that happens there every year, we got a bunch of fun things attached to the rooms we booked in the Marriott Village, one of them being free passes to the mini golf course on the Disney location. There was so much physics involved in the whole process, the main one i witnessed was the precise way to apply a force in such a way that the ball went in the direction you wanted it to. it was quite funny watc
My team mates and I were talking recently about what sounds we loved to hear while we were playing. most of the time we talked about how we could never hear our coach yelling at us from the side line, or how the sound of the ball against the back board of the cage was our worst or favorite sound depending on who scored. We also know the pain caused by the sound of two sticks hacking against each other. Sound is produced by air particles moving through a medium that cause a vibration that our ear
Waves in water are produced in many different scenarios. For example, when someone goes to the beach and decides to skip rocks, they produce a wave in the water. The water particles then move and continue to move creating a mechanical wave. these kinds of waves require a medium to pass through. who knew such a fun experience could experience so much physics.
