Physics of Catapults Essay

Many various muskets were used as well as cannons. They would have a fixed blade like a spear point on the end of the musket that is called a bayonet. They would use it like a spear

and the hand continues through its motion. Angles were placed on each still shot at the

9. The total energy is constant for most of the time until the ball is released and caught up and down in free fall, because extra force of the person actions changes the energy. The energy should remain constant because the kinetic and potential ratio energy

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

There are many approaches to this problem. The most common method is creating a separate air chamber using an empty soda bottle. A weight drops on this bottle to exert air pressure. This air pressure is then used to launch a projectile, adjusting the height of the weight as needed. Although easy, this method is too imprecise and will yield inaccurate results. To begin, it is needed to learn about how air pressure is created and the best way to achieve it. After

This is one of the first actions on a firearm that was more than simple hand cannon. The first recorded use of this kind of firearm was in 1364 according to the timeline from PBS history deceives website.

During its use by the Union army, the weapon was still in its earliest stages. Although the Confederate army did not adopt this specific weapon, they had similar ideas such as the Raines grenade, which was similar in appearance, but completely inadequate for battle. Instead of cardboard fins for a stable flight, the Raines grenade had a cloth streamer.

A few years of development and a patent later, the minie` ball was ready for combat. In the 1850's, James H. Burton, a master of arms, made a few alterations such as slightly lengthening the bullet and thinning the walls of the hollow base. These alterations made the minie` ball much easier and cheaper to mass-produce; this is what was used by the blue and gray's out on the battlefields.

Tools such as harpoons could be used to safely kill prey from a distance. How-ever the real advantage of the harpoon was that it didn’t become detached once it struck the animal, it would instead remain in tack and function as a marker to track animal. Marking an animal which would submerge themselves once attacked would have prevented losing the animal. This would have been most helpful in whale hunts. Other weapons included bows, darts, and spears specialized for killing birds. The shaft of these weapons would have been constructed out of either wood or the more readily available

They were pretty late invention but the bow and arrow was an ultimate stone age weapon, in some parts of the world they have only been in use for 30,000 years or so. This weapon needed a number of inventions to occur before it could be finalized. First of all they needed very strong tine or string, they needed a sharp stone tool to shape the bow and the arrow and the possession to split very sharp, fine stone for the arrow tips. The skill to capture or kill prey from a distance gave our stone age man a huge advantage.

The player has now compressed the spring in the ball shooter. The ball sitting in the ball shooter is at rest. It will be at rest until acted on by an unbalanced force. This is Newton’s first law of motion, the law of inertia (Kirkpatrick and Wheeler p31). The ball shooter is then released the spring decompresses and strikes the ball sending it up the incline to the top of the pinball playing field. The strike on the ball is called the impulse. The time interval it takes for the ball momentum to change. Since the ball has no momentum because it has zero velocity the ball shooter transfers its momentum at the impulse (The Ball Shooter 2003). This also takes place in the time frame of about a second.

Handheld weapons represented a large portion of the weapons used during 16th Century warfare (Iannuzzo). Most commonly used was the sword. Throughout the middles ages, metals were developed to withstand more abuse and thus became more effective (Iannuzzo). The metals now had to strong enough to pierce through the newly developed armor of the time (Revell, "Armour"). The use of carbonized iron, which was heated, beaten, and cut the process repeated many times over to form a solid and durable and lighter than previous swords. The double edge sword was far superior in strength and sharpness of the other swords of the time (Grolier). The 16th century also brought forth the use of flamberge sword that had an undulating cutting edge, that was believed to be able to easily pierce the armor, but was too awkward for battle and was eventually abandoned. By this time the Great sword, sometimes over six feet in length, were being deployed. This sword was deadly only because of the pure size of it. The great swords required enormous strength just to hold and even more to be effective. Eventually the great sword became too awkward to use in battle just as the flamberge. These two inferior swords took a back seat to the smaller and more agile estoc sword. The estoc had a

They made the Battle Axe by a knot in a root or branch with a convenient to make a good battle axe. also would put frog poison on the darts and put them in the blowgun. Stone weapons, tomahawks and battle hammers were made from rocks of the correct overall shape by sharpening one edge and grinding a binding groove around the stone using other, harder stones.

The history of weapons started centuries ago when cave people initially developed a weapon called a bow and arrow, for hunting purposes. They created this weapon from yew or elm for the bow and the arrow’s shaft, and used animal ligaments, or sinew to add tension to the bow. Archeologists have also found arrow heads made of sharp rocks and angled bones from different types of animals. These artifacts are all over the world displayed beautifully in museums to make new civilization realize the important role weapons have played in daily life.

Lawn Bowling, also known as Bowls, influenced today’s modern sport called Bocce Ball. Bowls originated from the Romans and “Descended from the universal pastime of throwing rocks or pebbles at targets on the ground” (Leibs 73). By the beginning of the Renaissance, this sport was popular among all classes of society. Some popular equipment that was used in the game was weighted balls, the jack, and the Trigg. Each player had four wooden balls, with a
