...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.

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....

Chapter 2 Theory Motion: In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of velocity, acceleration, displacement, and time. Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in...

Which of the following is most likely the approximate volume of the room? a. 3 m3 b. 30 m3 c. 300 m3 d. 3 000 m3 C2. When SI units are plugged into an equation, it is found that the units balance. Which of the following can we expect to be true for this equation? a. The equation will be dimensionally correct. b. The equation will be dimensionally correct except sometimes in cases when the right hand side of the equation has more than one term. c. The equation will not be dimensionally correct. d. All constants of proportionality will be correct. C3. How long has it been that scientists have accepted that the nucleus of the atom consists of neutrons and protons? Think of your answers in terms of order of magnitude. a. about a decade b. about a century c. about a thousand years d. since Aristotle C4. Consider the sine of any angle between 30° and 40°. If the angle were doubled, what would happen to the sine of the angle? a. It would double. b. It would more than double. c. It would increase but be less than double. d. In different cases, it could do any of the above. C5. There are other ways of expressing uncertainty besides significant figures. For example, suppose a quantity is known to have a value between 20.4 and 20.0 and our best estimate of the value is midrange at 20.2. We could write the number as 20.2 +/- 0.2 and say that the number has a 1% uncertainty. We would...

Abstract This paper presents solutions for one requirement of autonomous characters in animation and games: the ability to navigate around their world in a life-like and improvisational manner. These “steering behaviors” are largely independent of the particulars of the character’s means of locomotion. Combinations of steering behaviors can be used to achieve higher level goals This paper divides motion behavior into three levels. It will focus on the (For example: get from here to there while avoiding obstacles, follow this corridor, join that group of characters...) middle level of steering behaviors, briefly describe the lower level of locomotion, and touch lightly on the higher level of goal setting and strategy. Introduction Autonomous characters are a type of autonomous agent intended for use in computer animation and interactive media such as games and virtual reality. These agents represent a This stands...

Organoleptic properties, nutritional value, safety, and aesthetic appeal varies with food deterioration. The food is subjected to physical, chemical, and biological deterioration respectively. Various causes of food deterioration are as follows a) The growth of micro-organisms (bacteria, yeast, and mold etc.) b) Activities of natural food c) By Insects, parasites, and rodents d) Temperature (high or low) e) Dryness or Moisture content f) Air (mostly oxygen) g) Light h) Time (King, 2004) Furthermore, the major types of food deterioration are:- a) Microbiological spoilage. b) Enzymatic spoilage c) Chemical spoilage d) Fat oxidation e) Environmental spoilage EXAMPLES OF FOOD SPOILAGE AND FOOD PRODUCTS TABLE:- It shows various types of foods having spoilage under various conditions Food preservation involves the a) Use of heat b) Cold c) Drying (water activity) d) Acid (pH) e) Sugar f) Salt ...

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science 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 Yoga Sutras of Patanjali Introduction, Commentaries, and Translation What are the Yoga Sutras and who is Patanjali? Over fifty different English translations of the Yoga Sutras are extant, standing as a human testament to how Universal Truth is celebrated in terms of a rich diversity. Rather than the common and external type of knowledge (emanating from book knowledge), the following translation and commentary are a result of an intimate familiarity and direct experience both with an authentic yogic tradition and with western culture, psychology, and language that has been refined, tested in fire, and integrated for over thirty five years of intense practice (sadhana). This work is dedicated toward revealing the universal message of authentic yoga that the sage, Patanjali, first wrote down approximately 2000 years ago. Patanjali is not the inventor of yoga, but rather yoga's most popularly known scribe. What has become known simply as the "Yoga Sutras" (sutra means thread) or almost equally as common, as the "Yoga Darshana" (the vision of Yoga), is actually a compendium of an ancient pre-existing oral yoga tradition consisting of both practical advice and theoretical context. The most accepted format of the Yoga Sutras consists of four chapters (called padas) written in the Sanskrit language approximately 2000 years ago in Northern India while utilizing the terminology of the time, i.e., Samkhya philosophical trappings. The dates ascribed to the Yoga Sutras...
