Physics Snow Day Fort

Even though the weather has been in the single digits the past week, building the snow fort was not as bad as I thought it was going to be. I had dreaded building this fort because of how cold and gross it was outside, but eventually I thought about it and it didn't seem as bad. Using snow from the past snowstorm we just had, I built a fort that could fit one to two people (depending on the size of the person).

The first step for building the fort was to plan out what I was going to building. I needed to think about what I was going to use and what I was going to do with it. Since there was already so much snow, I figured I would just use as much snow as possible and try not to use much more materials than that.

After I had an idea of what I wanted to build, I start working. First I piled up a big mound of snow, and then I got a shovel to dig a hole in it. I made the hole big enough for a person to fit through, but not too big. After I dug the entry way I started to make room inside the fort for people to sit. I started to dig on the inside of the fort on the left and right to make it wider for more people to fit. Once I finished that, I dug up the rest of the snow on the ground of the fort to make more room for a person to fit straight up.

Once I finished all my digging, I smoothed the fort out so it was even and comfortable for people to sit in. Then I put a trash bag over the hole to act as a cover. Overall there was a decent amount of room that one person could definitely fit in, even probably two people. Not only was this task something that got me outside, but it was fun to do.

Physics of Black Holes...Or Lack Thereof

Isabella Jacavone To comprehend how the universe works, we must dwell into the most basic building blocks of existence; matter, energy, space, and time. NASA's Physics of the Cosmos program involves cosmology, astrophysics, and fundamental physics intended to answer questions about the elusiveness of complex concepts such as black holes, neutron stars, dark energy, and gravitational waves. In this blog post, I'd like to elaborate on a subject that is very intriguing to me; Black holes. And more specifically, what would happen if we got near one. A black hole is anything but a hole, but rather an immense amount of matter compacted into an extremely small area. A black hole is caused when, hypothetically, a star four times more massive than our sun collapses into a sphere no bigger than 600 square km. To put that in perspective, that's about the size of New York City. B lack holes were predicted by Einstein's theory of general relativity, which showed that when a

Physics Behind Drone Flight

A drone flies by using its downward thrust and forcing air in a particular direction in order to sustain a certain speed as well as a specific height. In this video my friend and I had been flying a drone at exactly 4 mph which converts to 1.788 m/s. In this project, we will be determining the forces acting upon the drone in order to sustain a consistent flight in terms of velocity and height while excluding the effects of air resitance. The drone is flying at an angle of 28˚, this is found by extending the tilted axis of the drone to the horizontal and finding the angle with a protractor. From this angle we will be able to calculate the downward thrust and the acceleration of the drone that allows it to maintain its height and velocity during flight. When the mass of the drone is taken it results in 734 grams or .734 kilograms, which will also be used for the calculations within the project. The freebody diagram pictured above will alow us to derive the force equations f

Aerodynamics of a Golf Ball

One may wonder how a small golf ball can travel at incredibly high speeds for such long distances. While the swing of the club is a major component, the structure of the golf ball is quite important. Unlike a baseball or tennis ball, a golf ball has dimples all over it (usually 336 dimples). These dimples allow the golf ball to travel without facing much air resistance. This diagram shows how air travels around the golf ball. The dimples on the golf ball also prevent drag that would occur in the wake region, resulting in further distance. Also due to the contact with the club during the swing, the golf ball has backspin during its entire flight. This diagram shows the motion of the golf ball mid flight with the lift force of F. There are hundreds of different types of golf balls that a player can choose. Some show little affect to a player's game while others can alter their performance completely. Personally, I prefer Callaway Supersoft golf balls, but it is entirely
