# The Physics Of The Earth Tilts Essay

840 Words Oct 10th, 2016 4 Pages
The earth tilts possibly due to being hit by an asteroid billions of years ago causing it to tilt in the sun 's orbit. Therefore its axis that should be completely vertical top to bottom) tilts. The earth completes one turn daily therefore all the world will receive sunlight and will enjoy the changes of season because of this tilt. It has nothing to do with how close it is to the sun but because the axis is not straight. The axis stays tilted in the same direction as it orbits around the sun that is why only certain parts received more sunlight on a specific time of day and in the year (seasons). The sun has to go through many layers that filter some of the more harmful radiation that is emitted and allows the earth to provide an abundance of life and food. The 6 layers play a particular part into what rejects or absorbs certain dangerous light waves. The first and very last layer in our atmosphere is the exosphere and has no breathable air and is extremely cold, below that lies the thermosphere that has very hot molecules that capture the radiation becoming charged and increase in temperature, but because they are scattered and not packed in tightly they are unable to transfer the heat, The next bottom ;layer is the middle layer known as the “mesosphere” where all the gasses are mixed , followed by the stratosphere that contains the very well known ozone that captures intense UV Rays from the sun which protects our atmosphere known as the troposphere. Within the…

In gymnastics, the physics involved in energy, Newton’s Laws of Motion, and angular momentum each contribute immensely to being successful in the Olympics. Learning how to master these physical science concepts can aid in becoming a strong olympic gymnast. To begin, there is the running start; this is where energy plays a major role. During a gymnast’s running start for a vault, she gains kinetic energy, which is, simply put, the energy of motion. Looking at the equation for kinetic energy (KE =…

According to Instructor: Joao Ricardo in the Physics class that I attended on Tuesday and Thursday, the teacher passed a paper for students and the students checked their attendance by themselves and wrote their names and signed on the paper. Then, he had graded the mastery test and gave them back to students to look at the feedback given by the instructor. After one hour, he took the mastery test’s sheets to keep them as students’ records. He also had graded the big test about light. In…

The Physics Behind Bicycles A. Laws: There are 3 laws of motion that apply to the function of a bicycle. Newton 's first law would be the "Law of Inertia". According to "Law of Inertia", an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This force is applied when the bicycle is in motion and it doesn 't change its speed or direction…

Copernicus also noted that clouds and falling objects are not affected by the rotation of the Earth because they obey the same nature as earth. 9. “Whether Many Movements can be Attributed to The Earth, and Concerning the Center of the World.” Copernicus argues that the irregular patterns the planets follow make it apparent that the earth is not at the center of their rotation. Additionally, there is no reason why Earth is the only spherically shaped body in the world with gravity (and therefore the center…

Physics is very relevant to football. Mechanics is the part of physics that relate to football. When you throw a football, physics is being used. You make adjustments to your body to where you want the ball to be. When you punt or kick a football, it is moving with the velocity it was given depending on the force it was given from the person. The football will follow a parabolic direction after a kick or throw. You won’t know that you’re using physics because it comes naturally. When blocking and…

The physics behind the average golf swing is quite complicating yet so simple at the same time (real-world-physics-problems.com). Its not necessarily the harder you swing the club the farther your shot goes, it has other factors to deal with as well, such as the rotation of the shoulders creating the torque on the club head. Swing speed does play a very big factor in the distance of the ball though, but you must have everything in the exact same sequence as you would a regular golf swing but speed…

The reason people can see through windows and not concrete is because glass is transparent to visible light while concrete is not transparent to visible light. Today, physics can explain how transparency works and allows people to apply the physics to everyday applications that make life better. Light reacts differently with different materials. Three things can occur when light encounters a medium. First, the light ray can be absorbed by the material. According to William Harris, absorption occurs…

No one would have believed, in the last years of the 19th century, that physics was heading for a crisis. It seemed like all the large questions had been answered. The behaviour of bodies, from asteroids to galaxies, was predicted by Sir Isaac Newton 's laws of gravity and motion. Magnetism, electricity and light were linked by James Clerk Maxwell’s Equations. The understanding of the atom had reached the plum pudding stage, where an atom was a globe of 'stuff ' with the positive and negative charges…
