Friction is a force that fights against any motion between two surfaces that are in contact with each other, and is a delaying force that resists motion in the opposite direction to the motion of that object. There are four categories of friction which are; Rolling, Sliding, Fluid, and Static Friction. Rolling Friction occurs when an object rolls over a surface, such as a soccer ball getting kicked across a grassy field, and eventually will slow down more quickly than a ball kicked across a smooth

Centripetal Force and Centrifugal Force The component of force that acts on a body in curvilinear motion which coordinates towards the focal point of curvature or axis of rotation can be defined as Centripetal force. Whereas, centrifugal force is defined as the apparent force, equivalent and inverse to the centripetal force, draws a turning body away from the focal point of rotation, which is caused by the inertia of the body. CONCEPTS These forces have different concepts where one of the forces

One problem I would love to work towards solving is that most people assume the hula hoop is a child’s toy, mere playground equipment for ages three to twelve. When I tell people I love to hoop they may think I’m referring to basketball. When I explain that hooping means hula hooping I open myself up to receiving strange looks from people, sassy comments, or just plain confusion. I have heard people say things such as “You deserve a medal if you can keep a hula hoop up for more than three rotations

Introduction: There are two (main) different types of friction: static friction and kinetic friction. Kinetic friction is the movement of an object as it slides on a surface due to applied force upon the resting object. Static friction is the friction between a motionless object and the surface on where the object is resting on. A force must be applied to make the object move; which will be done in my experiment. This experiment is to observe what angle presented will allow the mass to slide down

Determining the Spring Constant of a rubber band through a slingshot From the beginning I knew I wanted to start a Physics related to motion. I’ve always had an interest in using devices to fire an object at greater speeds than throwing. The reason I chose to use a slingshot was that I never used one before in my life. Using motion to determine the spring constant at a certain force allows me to have a problem to which I would solve using something I enjoy. Used in the early times for hunting and

I have loved competition ever since a young age. I have several friends that I love to compete with. We compete everyday, whether it is sports or if it in school games. We have been competing for as long as I can remember. Although my friends and I believe that competition is a great thing at school, some parents and schools are trying to argue that we should remove competition from school. They believe that kids can get hurt, but a child can get hurt just as easily walking up the stairs as

Data Analysis Does the type of ball affect how far it rolls when rolled down a ramp? The hypothesis for this experiment was “If the different types of balls are rolled down a ramp, then the soccer ball will roll the farthest.” The independent variable, the variable that was intentionally changed, were the types of balls. The distance each ball rolled is the dependent variable. The experimental group includes the soccer ball, the basketball, the tennis ball, the golf ball, the marble, the baseball

to the teachings of physics. While the situations and events that happen to Wile may be hilarious and believable to a child, once someone has gone through physics and re-watches the clips, that person starts to see the falsifies within the cartoon series. In this relatively brief 14-minute clip that is composed of various Looney Toons sketches between Wile and Road Runner, Wile encounters many setbacks to his plan of pursing his prey, Road Runner (Jones et al., 2011). The physics teachings of Newton’s

As we know a vehicle moves due to the frictional force between the tyre and road. When we apply brakes, the brakes apply a torque in the opposite direction as that of friction and the wheel gradually comes to rest. This is how normal brakes work. Now, whenever we are traveling on smooth surfaces like snow where the friction coefficient is low and hence less frictional force. When a brake is applied in these conditions or even when you brake hard on a regular surface the amount of torque is so high

St. Patrick’s Day is an Irish cultural/religious celebration, and because of this you just never know what to expect. Here is what may happen to you this St. Patrick’s Day, Saturday the 17th. Aries (March 21-April 19) You’ll go to an amusement park. It’s never been a secret that you love amusement parks. You love thrills, to go fast, for wind to run its fingers through your hair and push your head back. You love to feel like you’re flying, like you’re a free bird able to soar across the sky. Only

each other. Whenever an object moves against another object, it feels frictional forces. These forces act in the opposite direction to the movement. Friction makes it harder for things to move. Friction plays a major role in actual roller coaster physics, where mechanical energy which is the sum of potential and kinetic energy is not conserve. There are four types of friction in roller coaster. First of all, rolling friction which occurs between a rolling object and the surface it is rolling on. The

As a student of physics and mathematics, I want to talk about a prevailing problem in this field. There has been a decreasing interest in the field of physics and mathematics among the young minds to pursue it as a career. At Howard University’s department of physics and mathematics, the number of students is lower than any other departments. The number of students in Engineering is significantly larger; Chemistry and Biology also have appropriate number of students. Those who want to pursue medical

interest in farming, Newton was the top student in his class, and the headmaster of his school willed Newton’s mother to allow him to finish school (Wilson 2016). Eventually, Newton became known for his work in many fields, including mathematics, physics and philosophy. Newton continued onto college, starting at Trinity College in Cambridge in June of 1661. There, Newton studied the teachings of his many predecessors- Galileo, Descartes and others. After studying the teachings of the scientists and

He will counter that the laws of physics are not actually real; that they are just names given to regularities of the world discovered and documented by conscious beings (nominalism); or that they are mere concepts in the (material) mind—like the Pythagorean Theorem or the cardinal numbers—concepts

AP World History – and the sciences – taking Physics, Chemistry, and Principles of Engineering. Outside of class, I was involved in student leadership through groups like the Minnesota Association of Student Councils and the Sartell School Board, but not in STEM extracurriculars due to a lack of programs. These experiences drove my interest in studying both engineering and government, but I was mostly

ultimately had to drop out of high school. However Pauling was able to save enough money to attend the Oregon Agricultural College, where he became very interested in chemistry, mathematics and physics. He was such an intelligent student that he took time off from his own education to teach an introductory chemistry course at the institution. He would become known as a gifted, charismatic speaker who was able to make even the most advanced chemistry concepts interesting, his students loved him; and

Linus Pauling played an important role in the pioneering in chemistry. In matter of fact he received a Nobel Prize in 1954 and also in 1962. The Nobel Prize in 1962 was for the development of quantum mechanics during the 1920s. His Nobel Prize in 1954 was for his research in nature of the chemical bond and its application to the elucidation of the structure of the complex substance . Linus Pauling was born in Portland, Oregon. He was born in the year of 1901 on February 28th. His family came from

contributions to the theory of finite differences such as f(x+b) – f(x+a). He used the fractional exponents and coordinate geometry to derive these solutions to Diophantine equations, which are algebraic equations with only inter variables. Both the introductory to calculus and the binomial theorem, contributed to modern day mathematics. They can be used in real life situations. For example, architecture. These two concepts would allow calculation of magnitudes of projects used in architecture that would

Tylar Selensky MATH1303 Women in Mathematics September 30th, 2017 Women in Mathematics Throughout history women have played major roles in the development of mathematics. Over the course of several centuries, women have made a major impact on the world of mathematics and ability for young girls to be able to study mathematics. Many were pioneers of education, processes, and helped pave the way for women to gain notoriety for their accomplishments. Charlotte Angas Scott and Sofia Kovalevskaya are

general theory of relativity have been detected directly at last. Einstein was right. In 1905, Albert Einstein found that the laws of physics are the same for all non-accelerating observers, and that the speed of light in vacuum did not depend on the motion of all the observers. This was the theory of special relativity. It provided a new framework for all of the physics and introduced new concepts of space and time. Einstein then invested 10 years to include acceleration in the theory and published
