...Forces and Motion For Students of Baldwin Wallace College Spring Semester 2011 Monday – Wednesday 10:00 – 11:15 am Room 139 Wilker Faculty Richard Heckathorn The materials for this course were organized and edited by Richard Heckathorn using materials from a program called Operation Physics and includes materials developed by him. The original OPERATION PHYSICS activity sequence to improve physics teaching and learning in upper elementary and middle schools was funded by the National Science Foundation. Original Material Copyright 1992 by American Institute of Physics Materials edited and photoduplicated with permission. FORCES & MOTION INTRODUCTION WORKSHOP LEADER’S TOPIC INFORMATION INTRODUCTION TO FORCES & MOTION An understanding of force and motion is fundamental to the study of almost all other physics-related topics. Yet it is a topic often overlooked or only cursorily introduced in elementary and middle school science, even though it is a topic typically identified for inclusion in the curriculum for these grades. A primary reason for this is that many teachers do not feel comfortable about their own understanding of the topic. Consequently, this may be the most needed of all of the OPERATION PHYSICS workshops. This workshop leader’s notebook is divided into two parts: PART ONE Motion Part One begins by introducing participants to the concepts of space and time....

By making the book available in these various media at a cost ranging from free to cheap, I enable the text can be used by students all over the world where each student can pay (or not) according to their means. Nevertheless, I am hoping that students who truly find this work useful will purchase a copy through Lulu or a bookseller (when the latter option becomes available), if only to help subsidize me while I continue to write inexpensive textbooks in physics or other subjects. This textbook is organized for ease of presentation and ease of learning. In particular, they are hierarchically organized in a way that directly supports efficient learning. They are also remarkably complete in their presentation and contain moderately detailed derivations of many of the important equations and relations from first principles while not skimping on simpler heuristic or conceptual explanations as well. As a “live” document (one I actively use and frequently change, adding or...

...in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses. They lie outside the realm of science. 11 Science, art, and religion can work very well together; like strings on a guitar, when played together, the chord they produce can be a...

...motor vehicle after taking a substance which alters the central nervous system. This includes over-the-counter, prescription, and of course, illegal drugs. The following categories of drugs have known side effects that include impaired attention, reaction time, and vision: * Antihistamines * Pain Relievers * Tranquilizers * Hallucinogens * Stimulants * Narcotics It is very dangerous to combine alcohol and other drugs. Synergism occurs when the effect of one drug is enhanced by the presence of another drug. A multiplying rather than additive effect may occur. It takes more ounces of beer than whiskey to become impaired, but people tend to drink more beer (total ounces) than whiskey. Regarding the servings of assorted alcohol beverages, they all have differing amounts of alcohol. Beer actually has more alcohol than whiskey and coolers are even stronger. There are also an infinite number of ways to mix alcoholic beverages so a drink by drink comparison can only be made when size and alcohol content of the drinks involved are known. Alcohol is a toxic substance. The use of alcohol has no benefit to the body or society. Abuse or excessive consumption of alcohol or other drugs affects the physiology of the body in many ways. If a body becomes accustomed to the presence of alcohol continuously, a physical dependence develops and changes in the way organs and body systems respond to a drug. Addiction is “a state of periodic or chronic impairment...

...its roads the safest in North America, and that's why the Ministry of Transportation has introduced a range of measures to improve the behaviour of all drivers, including new ones. In 1999, more than 860 people were killed and more than 84,000 injured on Ontario roads. The social and economic costs of these collisions have been previously estimated at $9 billion annually. Many collisions are caused by driver error - behaviour like following too closely, speed too fast, failure to yield the right of way, and improper turns and lane changes. And statistics show that new drivers of all ages are far more likely than experienced drivers to be involved in serious or fatal collisions. Ontario campaigns against drinking and driving, aggressive driving and promoting the correct use of seat belts and child safety seats are making a difference. Graduated licensing, which lets new drivers gain skills and experience in low-risk environments, is also helping to develop better, safer drivers. The Driver's Handbook Online gives new drivers the basic information they need about learning to drive in Ontario: the rules of the road, safe driving practices and how to get their licence to drive a car, van or small truck. The ministry recommends that all drivers would benefit from taking a course in advanced driver training....

...UNIT 1- CAR BODY DETAILS Cars can come in a large variety of different body styles. Some are still in production, while others are of historical interest only. These styles are largely (though not completely) independent of a car's classification in terms of price, size and intended broad market; the same car model might be available in multiple body styles (or model ranges). For some of the following terms, especially relating to four-wheel drive / SUV models and minivan / MPV models, the distinction between body style and classification is particularly narrow. Please note that while each body style has a historical and technical definition, in common usage such definitions are often blurred. Over time, the common usage of each term evolves. For example, people often call 4-passenger sport coupés a "sports car", while purists will insist that a sports car by definition is limited to two-place vehicles. Body work In automotive engineering, the bodywork of an automobile is the structure which protects: ⦁ The occupants ⦁ Any other payload ⦁ The mechanical components. In vehicles with a separate frame or chassis, the term bodywork is normally applied to only the non-structural panels, including doors and other movable panels, but it may also be used more generally to include the structural components which support the mechanical components. Construction There are three main types of automotive bodywork: ⦁ The first automobiles were designs...
