The visit to the LA’s space shuttle highlighted the story that began in a small town of Palmdale, an hour drive from Los Angeles where a space shuttle was built in a galaxy called the Milky-Way. The space shuttle flew over 100 million miles and was in the outer space for over one year of its lifetime. The dynamic shuttle finally retired to its sunny hometown and continues to delight and educate school children. The Endeavor made its final historic flight in 2015 followed by a breathtaking road…

Softball is a game enjoyed by millions of people around the world. The game is played on a diamond-shaped field that involves two teams of players. The teams are filled with players who pitch, hit, and field in order to get runs to score. While the sport is often just seen as a game of skill and strategy, there is also a deeply ingrained principle of physics in it. Understanding the physics behind the beloved game can help provide valuable insight into enhancing a player's abilities. When I was…

1‑inch‑diameter torsion springs made of nylon rope will be capable of propelling a golf ball at least 200 feet. To accomplish this task, we will apply the principle of conservation of energy and the projectile range equation. Our model of the mechanical system consists of the two arms, sling, and projectile, with applied torques at the base of each arm representing the torsion springs. The two principal forms of energy relevant to this problem are kinetic energy, the energy associated with a…

would be a risk of adding extra force upon the mass causing the landing position to change. The projectile was able to be launched because when the string was burnt on the opposite end to the razor blade the mass was able to swing at certain velocity allowing the string to be cut causing the projectile to be launched into the air and if calculation and measurements are correct, will allow the projectiles to land in the predicted area. (See figure…

down until the counterbalance was high in the air. The energy was stored in the potential energy of the counterbalance. The sling was then loaded with projectiles. The rope was released and the counterbalance plummeted downwards. The potential energy is converted into kinetic energy and, when the long arm is brought to an abrupt stop, the projectile continues with the velocity produced by the kinetic energy. The Trebuchet was the most feared and hated siege weapon. The men who manned the…

A catapult is a ballistic device that is uses to throw projectiles over a great distance. Although the catapult has been used since ancient times, it has proven to be one of the most effective mechanisms during warfare. The word 'catapult' comes from the Latin 'catapulta'. Castles and fortified walled cities were common during this period – and catapults were used as a key siege weapon against them. As well as attempting to breach the walls,flammable missiles could be thrown inside—or early…

hazards: The Lawn mower. The lawn mower can fling rocks, sticks, and other objects at high speeds. Normally your eyes are out of the way of these projectiles. However, they can ricochet off a wall, tree, or other large object. You may need to walk in front of your mower to remove debris from its path. These situations expose your eyes to projectiles from your mower. The Power lawn trimmer. The lawn trimmer is quieter and smaller than a lawn mower, which make it seem less dangerous. Yet this…

into the flintlock pistols and rifles used during the revolution and civil wars, and to the modern firearms we have today. To this day guns still work the same as they did many hundreds of years ago they still use a gunpowder explosion to propel a projectile at the enemy, except they are much stronger than they used to be. Without gunpowder we would not have as much protection for our country such as firearms, tanks, and other gunpowder powered weapons. A weapon that did not require gunpowder…

rounds in the country, they differ distinctly in their hunting applications, long-range ability, and produced recoil. Perhaps the biggest difference between these two cartridges is in their hunting applications. The .22lr fires a small, slow-moving projectile that leaves a tiny exit wound. Theses attributes make the round better utilized for hunting small game, such as squirrels, rabbits, foxes, raccoons, beavers, and opossums. At the opposite end of the spectrum, the .30/06 spits out a…

Once upon a war Archeologists have recently uncovered evidence of what may be the oldest known incident of warfare among humans. Dating back to around 10,000 years ago, the remains found on the shores of Lake Turkana in Kenya are also significant because they belong to a hunter-gatherer society rather than to settled agricultural peoples. Archeologists and anthropologists have long believed that because hunter-gatherer societies are relatively egalitarian, they are also less violent. The…
