Forces are extremely important in a roller coaster, as they create the different sensations throughout the ride, and also help to hold you in your seat for safety. Forces on a roller coaster are measured in g's, which is how to measure gravity on the ride. The change of g's in different situations is what creates the different feelings and thrills you get on the coaster. When our marble is released at the top of the initial hill, energy is transferred from potential energy to kinetic energy.…

Conclusion The hypothesis was that extreme temperatures would affect the bounce height of a basketball. This hypothesis was accepted. The average bounce height for the regular basketball was seventy three and 3 tenths repeating. Sixty two and six tenths repeating was the average for the frozen basketball. The average was eighty-three and three tenths repeated for the heated basketball. We believe that these results are present because air molecules will expand in warmer temperatures and they…

Copernicus was the most prominent astronomer in history of the world. He landed in the Renaissance period in North Poland from 1473 to 1543. Copernicus was cared for by his paternal uncle and attended multiple universities before, he died in 1543. Copernicus brought up the idea of a heliocentric solar system, and wrote a book that is still considered the best book ever written on astronomy. He has prompted the work of many scientists after him and we still believe in a heliocentric universe.…

Imagine sprinting for 40 meters while holding a pole up to three times your height. At the end of the runway you propel yourself up as high as you can to fly over a bar. The four stages include prep and stance, acceleration, pole plant, and clearance and landing. The pole vaulters stance is the set up in preparation to begin accelerating towards the platform. The 40 meter dash while holding the large pole is a phase known as approach. The stance swing occurs during the pole plant which then…

Have you ever needed to do a certain simple task, but wished there was a machine to do it for you? The purpose of a Rube Goldberg machine is to create a complicated system in order to complete a tiny, simple task. What is a Rube Goldberg machine you may ask? A Rube Goldberg machine is an over- engineered contraption that uses a chain reaction to accomplish simple tasks such as turning on the music, pouring a glass of water, etc. This specific Rube Goldberg machine’s task is to move the last…

most powerful researchers ever and a key figure in the logical upheaval. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first distributed in 1687, established the frameworks of traditional mechanics. Newton additionally made pathbreaking commitments to optics, and he imparts credit to Gottfried Wilhelm Leibniz for building up the minute math. Newton's Principia figured the laws of movement and all inclusive attractive energy that ruled…

Soccer is a sport that involves two teams of 11 players who strike a football with their feet. When the players kick the ball they can affects the way the ball spins in the air. Factors that affect the way a ball spins include: wind drag, the way the ball is struck, and friction. These affect it due to the change of the air-flow over the ball, which occur when the ball spins in both a translational and rotational motion. This is due to the magnus effect and bernoulli principle occurring when the…

Ava Lilienthal Science Barcus 7-4 The Physics Behind Soccer Soccer really has a lot to do with science. From Newton’s laws of motion to the momentum of the person kicking the ball, the drag force and the magnus effect, and even the air pressure in the ball. It is harder than most people think. Next time you watch a soccer game, or play a soccer game, think about the science in the game. First, Newton’s Law’s are present when the ball is kicked. His first law, an object at rest stays at rest…

The teardrop design makes it much easier to balance these forces. the only forces exerted upon the riders are the force of gravity and the normal force The force of gravity is at all times directed downwards and the normal force is at all times directed perpendicular to the seat of the car. Since the orientation of the car on the track is continuously changing, the normal force is continuously changing its direction. Feelings of weightlessness and heaviness are associated with the normal…

Differential Services When a car makes a left turn, the left side wheels naturally turn slower than the outside wheels on the right because the exterior wheels have to travel farther than the inside wheels make the turn. For this reason, tires have to be able to move independently and at different speeds to avoid slipping. This gives the car more power and control in the turn. A differential is a mechanical set of simple gears that allow the wheels to rotate at independent speeds, and to be…
