primarily as medicine and entertainment‚ Chinese scientists quickly realized gunpowders potential for engaging in warfare. “It was a component of flaming arrows and rockets and was used to fire projectiles” (Classroom). The bamboo tubes used to channel the explosive energy of gunpowder to launch a projectile was history first firearms. This new ranged weapon would revolutionize the way humans fought wars all over the globe. From ending the Medieval ages in Europe‚ to setting up the foundation of the

Catapults were first invented to hurl projectiles farther than any human could. They were effective as blockade weapons and vital on the battle fields (Alchin‚ 2012). The type of catapult used in this experiment is called a Mangonel catapult. Typical mangonels are powered by a torsion-type string‚ which is twisted when the catapult arm is pulled back. When the catapult is fired‚ the spring pulls the catapult arm back to its original position‚ launching the projectile (Alchin‚ 2012) The mangonel consists

In the 1868 St. Petersburg Declaration renouncing the Use‚ in Time of war‚ of Explosive Projectiles under 400 Grammes Weight‚ State parties agreed that ‘the only legitimate aim of war was to weaken military forces of the enemy and that‚ that aim will be exceeded if arms which uselessly

Special Weapon Effects Ceci n’est pas une sniper rifle! – It fires slow moving projectiles shaped like arrows. Always incendiary. Always spawns without a scope. Even though it is an E-tech weapon‚ it only consumes one sniper bullet per shot. Usage & Description When auto-targeting is turned on in the options menu‚ the snap-to targeting places the arc of the Longbow’s projectile immediately through a standard humanoid enemy’s head. The key is to not correct an aim for the head as normal‚ but to

Forts in ancient India Three major methods were used for the construction of ancient Indian forts. The first consisted of earthen ramparts. Often they were constructed of the sand which was dug out of the ditch surrounding the fort. The second of rubble with earth on the outside which was more sturdy. The third type of construction was with stone and masonry work. The last was the strongest. Often materials from demolished forts were reused in the building of new forts.[2] By 4 BCE‚ fortified cities

Experiment 3: Projectile Range Versus Angle EQUIPMENT NEEDED – Mini Launcher and steel ball – Plumb bob – Measuring tape or meter stick – Carbon paper – Graph paper – White paper Purpose The purpose of this experiment is to find how the range of the ball depends on the angle at which it is launched. The angle that gives the greatest range is determined for two cases: launching on level ground and launching off a table. Theory The range is the horizontal distance‚ x

misconception that BBs and pellets are only for the younger crowd. This was the case years ago before gunsmithing and technology started experimenting with other ways to push projectiles at high velocities.

"accurate" estimation that it will come within 11‚000 miles (17‚000 kilometers) to 9 million miles (14 million kilometers). The reasoning behind the wide range is due to the fact that they only had two years to track its progress. To further dispell conspiracy theorists‚ NASA has made an official report that there is absolutely no chance that this projectile will hit our planet in 2016. However‚ when it comes back again in 2017‚ there is a 1 in 250 million chance it will hit. That’s right‚ it’s coming back

The river flows east through the broad valley bottom‚ passing through two major mountain ranges before cutting through the foothills and entering the plains‚ where it merges with the Whiskey River. The valley floor consists of broad‚ well-drained glacial outwash terraces‚ above which steep mountain slopes rise to either rocky peaks or treeless
