Snow Day Blog 2

When assigned the snow day blog, I decided I wanted to recreate some of the practice problems we had done in class with balls crashing into each other.  I took a soccer ball and basketball, weighing .43 kg and .63 kg respectively.  I rolled the soccer ball into the basketball and observed what happened afterwards.
After video taping this collision, I used logger pro to calculate the velocity of each object before and after the collision.  Since the velocities differed throughout the course of the video, probably because of human error, I decided to use the approximate average of the balls.

Velocity of the soccer ball:
Velocity of the basketball:
Equations:
(.43)(1.5)+(.63)(0)=(.43)(0)+(.63)(1.1)
.645 kg m/s = .693 kg m/s

It is evident here that the momentum is approximately the same value, meaning that momentum was conserved throughout the collision.

Energy:
Soccer Ball: 1/2(.43)(1.5)^2=1/2(.43)(0)^2=.484 J lost
Basketball: 1/2(.63)(0)^2=1/2(.63)(1.1)^2=.381 J gained

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...

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 Supers...

What Would Happen if Everyone in the World Jumped at Once?

Hypothetical and far out questions are what create great physicists and allow for us to discover and test things that have never been thought of before. Even as kids, we let our minds wander and ask questions that we never knew could be proved or disproved by physics. One question that I, as a young questioning child, and many other highly regarded physicists ask is simple; what would happen if every single person got together and jumped at once? This situation is completely unlikely to ever happen, so the only way we could ever know what would happen is through physics. Okay, so lets set the scene. Everyone, all 7 billion people, could fit into an area the size of Rhode Island, so lets assume that everyone did  travel to the smallest state in the US.  Finally, in unison, all 7 billion people jump. The push against the earth doesn't affect the earth at all, considering the Earth outweighs everyone by a factor of a mere 10 trillion. Even if the Earth were rigid and responde...
