making a wave

Today in our lab we had a cylinder of water and some tuning forks and my group figured out a cool thing. When we struck the tuning forks and placed them in the water, the water splashed and made some waves. The tuning forks with lower frequencies didn't make those waves because they didn't have enough amplitude to move the water. The thicker and longer the tuning fork was the bigger the waves. The water splashed onto the cylinder of water and was quite amusing to me and my other group members. T

Projectile motion of food

Earlier tonight, I experienced projectile motion with my food. Yes, my food. Unfortunately while i was walking to the table to put down a bowl of rice, the utensil inside the bowl slipped and down feel the rice. It didn't go far because it wasn't going fast and because the rice didn't weigh a lot. It had a normal acceleration due to gravity but it felt like it was going so slow after i saw it start to fall. Almost the whole bowl of rice I was going to eat ended up on the floor but luckily my mom

Biking with Newton

Today I got the pleasure of going on a bike ride in the nice weather. Over the hills, across the streets, and down the hills, everything about the bike ride involve physics. Because there was little wind, my brother and I could go as fast as we want with little force opposing us. The lack of wind is especially helpful on the hills so you can easily conquer them! When we pressed down on the pedals to try and propel our bikes forwards, that was an example of Newtons law. The pedal was pushing back

Planes, trains and automobiles

Its scary to think about this, especially before a big flight down the coast, but honestly, how do planes fly? How is this big machine with tons of people, weighing literally tons, floating across the sky above the clouds? Well, I don't know either, but there is always physics to be found! Think about when you land in a plane and you get jolted back into your seat and can barely sit forwards until the plane actually slows down. Newtons law can come into play here. Because the plane is using the

Archery

Since this is titled archery most of you reading this will probably be getting ready to read a post about the arrow and the bow and trajectory and all that fun stuff that happens in the physics of archery. Im not going to talk about that just yet, but instead I'm telling about a cool physics discovery i made while sitting in gym class. I was holding my bow and twisting it back and forth so that it was swaying and then when i stopped the twisting motions, the bow kept moving!! I remembered physic

TRAMPOLINES

Trampolines possess a large amount of physics in them. First of all, the springs all around the bottom share the same spring constant, showing how much energy a person can have when the spring expands and compresses. The constant in the spring decides how high you can jump. If your spring doesn't compress much then the bottom of the trampoline can't go as low and in turn, you won't be able to jump as high. Your want thick, sturdy springs for your trampoline, but also those that will be flexible

Childhood memories

To bring back some childhood memories, you must think of swings, tag, climbing, and so many other actvities. All of those things we loved to do as kids, all involved physics. Lets look at swings. Energy is a main component to what we see about physics here. There is potential energy and kinetic energy and mechanical energy(which stays the same throughout the whole time). As we swing as seen in a parabolic arc, at the top when we are stopped slightly for a second, we have a large amount of potent

Gym Class heroes

Today in gym class, my team experienced a great deal of physics in the unit we just finished and my personal favorite, volleyball. Although we didn't have a team full of the best players, we had a lot of players who tried hard to help the team succeed. Most players on the court were experiencing physics while they were at it as well! Those who were moving around and were playing, were doing work on the ball and using their kinetic energy to do that work. The more power they had, the farther the

Back to Volleyball

At my tournament this past weekend in Connecticut, I saw physics all around me through volleyball. Not only was there physics in the players, but there was also physics seen in the spectators. Some spectators were recruiters looking for video on some players, and in that, there were many actions they took that involved physics. Those that were taking video displayed physics with their camera. The light energy from the camera is what we saw as onlookers into their actions. The camera's in and of

The weather gets bad and so do drivers

These days, with the snow consistently coming down, the roads keep getting worse and worse, along with the drivers. When the plows can't come and clear the snow, people tend to drive a significant amount slower so they don't slip, some may think this is overly cautious, but in reality, cars with summer tires still on their cars have a hard time driving in snow when they need snow tires. The winter tires provide more friction with the snow because of the lack there of with just the summer tires.

Sweet Spot Physics

As some of you know, I work for a company called the Sweet Spot at the Blue Cross Arena, Frontier Field and CMAC. The other day while helping the coffee stands set up, I noticed a key moment crucial to our set up at work. I was bringing down the supplies the coffee cart needed to the stand when it hit me how much physics was going on right in front of me. We have to carry a cart holding coffee pots, a large jug of water, creamer, a bin of packaged almonds and cashews, and three coffee dispensers

Physics in Running

While on a run with Quinn, i started to think of all the ways physics related to our current actions. We traveled all around town, up and down hills, on different surfaces like grass and pavement, and leaves, and lucky for us friction was a factor. Because of friction on our shoes and on the ground, we didn't slip and fall while running. While we kept pushing our legs into the ground with a force to keep us going, the ground was pushing that same force back onto our legs so we didn't fall throug

Phony Physics

Many people don't think about it, but there is simple physics in the actions you perform on your phone. For example when you hold the phone and type your acting on the phone with a force, and don't even realize that there must be a force acting back on your fingers or else your fingers would bend the phone. Also, we can see newtons first law in action when you unfortunately drop your phone, which all of us have done. Your phone won't stop its motion unless another force acts on it. Most of the t

Physics in Volleyball

In volleyball, there are many opportunities to see physics. There is friction, there is newtons first law and many other aspects. First of all, when a hitter goes up to jump to spike the ball, you're pushing down with a force into the ground, while the ground is also pushing the sam force back at you, so you don't fall through the ground. When your hand contacts the ball, the same thing happens, where the ball is pushing back at your hand and your pushing hard at the ball. That ball will stay in
