Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

TAP 601-1: Brownian motion Brownian motion (named after the botanist Robert Brown) is the presumably random drifting of particles suspended in a fluid (a liquid or a gas) or the mathematical model used to describe such random movements‚ which is often called a particle theory. The experiment of Brownian motion in a smoke cell is a classic experiment that gives strong circumstantial evidence for the particulate nature of air. Materials: ✓ Smoke cell‚ incorporating a light source

The Importance of Physics to Society Physics - the study of matter‚ energy and their interactions - is an international enterprise‚ which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: 1. Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature. 2. Physics generates fundamental knowledge needed for the future technological advances

Applications of Physics in Everyday Life By Steve Johnson‚ eHow Contributor Even walking manipulates physics‚ allowing people to proceed in a state of "constant falling." Physics extends well into people’s everyday lives -- imprisoning people within its forces. From each step a person takes to the evolution of the body‚ physics has several long-term as well as short-term effects and uses. For everyday living‚ many technologies have even exploited the rules of physics. 1. Simple Mechanical

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

Understanding Hofstede’s 5 Cultural Dimensions Geert Hofstede devoted over a decade to researching cultural differences and developed an internationally recognized model of cultural dimensions. There are five main dimensions of culture that serve as a guide to understanding intercultural communications‚ business‚ and effective social exchange. The five dimensions are Power Distance‚ Individualism‚ Masculinity‚ Uncertainty Avoidance‚ and Long-Term Orientation and were developed to provide a method

Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique
