throw that fast and accurate because he is bigger than you but there is much more to pitching than just the size of the pitcher. Even though pitching deals with the strength someone has to be a good pitcher you have to understand the physics and the force behind the actual pitch. In pitching you will need to know about the physics the human body even just pitching in general and speed and velocity. Physics play a very important role in baseball especially in the pitching aspect of the game.…

When a ball is kicked at its side it begins to spin around in its place according to the location of the kick. If it is kicked at the side and a bit towards the bottom the ball rises up in the air while spinning on its own axis. In the beginning it will fly exactly in the direction of the kick, and as it slows down due to friction with the air, the spinning motion will cause the air on one side to move faster than that on the other side and because of the Magnus effect the ball will then change…

If you are an avid fisherman, you need equipment that can keep up with your hobby. The Shimano Complex saltwater spinning reel provides you with the service and comfort you need for everyday or occasional fishing. This accessory is part of Shimano's Quickresponse Series. It is designed to be both lightweight and durable. Despite the light weight of this spinning reel, it provides remarkable stiffness. Shimano is moving from aluminum to graphite in their reels, so they benefit from modern,…

end of this lab we will figure out who's theory is correct. Hypothesis My hypothesis is that when a object is dropped it keeps a constant velocity the entire time it is falling on it it's a surface. Because when a object is dropped there is no force to make it accelerate in velocity. Conclusion The variables relate to each other…

The American Psychological Association (APA) defines three different levels of stress: Acute Stress, Episodic acute stress, and Chronic stress (APA, 2016). Acute stress is the most common of all. In regards to a Law Enforcement environment, atypical work shifts and high risk situations to the effects of post-traumatic stress disorder; the environment that police officers place themselves in take a psychological and physical toll on them and their spouses. Studies have revealed that law…

Family stressors can come in many different forms. For example, there are the normal stressors that involve getting married, having a baby, experiencing a new living situation or unemployment. These hard times are experienced by most families throughout the lifespan. However, there are also the abnormal stressors such as, war, economic collapse, natural disasters, or murder. These tend to happen to family systems at random and make more of a longer and lasting impact. The ABC – X Theory of…

Specify the sources (causes) of friction. The causes of friction in this lab come from three different sources. One is the string sliding over the pulley wheel. Another is the pulley wheel turning on its axle. Also, the string sliding through the hole; all these cause friction in our experiment. Glider on Frictionless Air Track Lab The acceleration of the glider can be calculated by tracking the speed as it passes through the two photogates. On the frictionless air track a glider is placed on…

Working hard is the definition of paystation. It is not an easy job, and that’s why I love it. I especially love the challenge of running the register and cleaning the dining room, but making sure everyone who comes in is helped quickly and has to wait as little as possible. I never thought working at Hy-Vee would make a difference in my life, though. Throughout my time working at Hy-Vee, I have learned a lot about working hard and being efficient, and applying that to my life outside of Hy-Vee…

flight there are four basic components; thrust, drag, lift, and weight. Newton’s laws and The Bernoulli Principle are the explanation of how everything works. Balance of force is a very important part of it. If the upward force is greater than the gravitational force imposed on an object, the object will go up. If the gravitational force is greater, then the object will go down or remain on the ground. World War I was the first time that airplanes were used on a large scale. At the start of…

number of tiny holes in the parachute affect its descension rate Introduction This experiment will determine if the number of tiny holes in the parachute effect will its descension rate.This science of this project includes newtons second law, drag force, gravity, velocity and terminal velocity . This experiments main focus is air resistance. Project rationale/ purpose In this experiment I will test if having small holes in a parachute help the parachute from falling as fast. This projects…
