What kids haven’t played with lasers? We have all loved the laser fights in movies like Star Wars. Who wouldn’t want wield a laser around while fighting an enemy. Did you know that the term laser came from an acronym meaning “light amplification by stimulated emission of radiation.”? It should actually be all capitalized but for simplicity it isn’t. The first working laser was actually demonstrated by Theodore Maiman at the Hughes Research Laboratories back in 1960. The strength of early lasers

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

surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater the tilt of the plane‚ the faster the rate which an object will slide down. Thus‚ if a physics cart is released on at a steep slope‚ the acceleration of the cart is expected to roll down the slope at a faster rate. As shown in figure 1‚ when a cart is released on an inclined plane‚ there’s always two to four forces acting upon the cart – the
