as many of you know I sit in chairs... a lot. And given the new information we have learned in physics class I can analyze the types of forces acting on me while I sit. Gravity being a constant is always acting and will continuously act on me as MG. Another force acting on me is the normal force -- this is the perpendicular force the sight of contact applies. The normal force must be equivalent to MG because I am not moving and have no acceleration leading me to the conclusion that I am in e
There is a video game called infamous. In this game the protagonist has the ability to manipulate electricity. he is able to project electric pathways toward specific objects. The question arises of if you would actually be able to do it. is it possible for someone to predict the pathway of electricity, ignoring the fact that the human body cannot hold large amounts of electricity. The answer to this question is yes, it is possible to predict an electrical path. Electricity will always go t
As many of you know I am a wrestler in order to stay in shape during the off season I lift weights. Using Newtons 3rd law I can tell you that the amount of force that pushes down on my hands is the amount of force I'd need to push back in order to just hold the weight(keeping it in equilibrium) But let's say I wanted to pump out a couple solid reps, you know build some muscle and get swole, then I'd need to apply more force in order to accelerate the weight in the direction corresponding to
Running is often used to stay in shape. running can be related back to newtons 3rd law. the force a runner puts back onto the ground is what the ground pushes back allowing the runner to be propelled forward. the more force applied on the ground the farther or faster someone will go according to newtons second law -- Fnet = MA. the more force applied on the ground by the runner (who has a constant mass) the higher his or her (lets not be sexist now) will go. running can also be related to
as some of you know I work at 2 ton ton'y where we have real good pizza. And the other day I had to walk to work in the rain. And so I was walking up Hudson and crossing th cross walk in front of wegmans, you know the big long one at the main entrance. as I was walking along I looked over my shoulder and noticed a car was waiting to pull into wegamans, and I didn't want to hold that nice man up I did like a half jog to get out of his way. I continued my walk to work as usual and right before I
we have been studying electricity in physics and to make it more interesting Mr. Fullerton brought in a vandergraph. Mr fullerton asked for volunteers to get shocked and of course my entire volunteered. In one hand I had Brenda and on the other I had Kara. Kara freaked out a little while we were charging up shocking everyone behind her in our line. This gave me the opportunity to shock the rest of the class . and so I raised my hand slowly toward the piece of metal holding the ceiling tiles
While in physics today we were coming up with stupid ideas that could barely be related to physics. and someone brought up the idea of a door, and that sprung an idea. Some doors like screen doors or doors in older public places is springs to make sure the door closes. Using physics I am able to calculate the amount of force I need to apply to open the door and the amount of force the door will be closing, if I am given the spring constant. however if I know how much force I apply to open the
Lets say I am wrestling man who weights 60kg. In order for me to take him down and score 2 points I need to pick up and return him to the mat. Using the potential energy equation found in our reference table (PE= mgh) I can calculate my opponents potential energy at the point in which he is level with my head. I would multiply 60kg by 9.81 m/s by lets say 1.5m. this would result in a potential energy of 441.45 joules. If I were to increase the height of my opponent his potential energy woul
I have a vishla, named cooper. he is about two years old and still has tons of energy. The other day I was getting home from work and as soon as I opened the door I was welcomed with a blast to the stomach. Sometimes my dog gets so excited when he sees people he forgets all his training. My dog has a very small mass, he is only about 40 pounds but when he builds up a large velocity his momentum takes the wind out of me with ease. There are times I wish he was just fat and old so I wouldn't h
Although at the moment my pool is frozen during the summer it is buckets of fun. regardless of the fact that it is only 4 feet deep we still jump in, but no diving. If no one enters my pool for a little bit you can see how smooth the surface of the water can be. But then when someone abruptly drops something in or even jumps into the pool you can watch as the waves slowly take over the pools calm surface. If we had the proper tools we would be able to measure the speed of these waves. All w
Gladiators are known as some of history's most ruthless warriors. during the roman times gladiators would be put in the coliseum and fight to the death. There are commons moves associated with winning a battle. one of these very popular moves is when someone picks up the other man above his head and tosses him to the ground. There is a lot of physics involved in this situation. in order for a gladiator to pick his opponent up he must apply more force than the weight of his opponent, which i
In Italian today a handful of people brought in food -- because its Friday -- and signora brought in some hot chocolate. along with this beautiful drink we call hot cocoa she brought mini marshmallows. And so while I sat back in my chair like a mob boss in a 1980s mafia film, I though to my self I bet I could make it land a marshmallow in my hot cocoa "from downtown". After a couple attempts I realized with a couple givens I have the potential to calculate every aspect about my marshmallow. U
while in the computer in the library I was very amused by what I saw in front of me. someone was watching dude perfect trick shots. these guys pretty much goofy around doing really cool stuff, while making a large sum of money of course. The episode I was watching in the library that one day was with epic bowling shots. and as I watched someone knock over all the pins from across a skate park with his bowling ball, I thought to myself wow that bowling ball probably has a lot of kinetic energy
