    HSC PHYSICS: SPACE * 1. “The Earth has a gravitational field that exerts a force on objects both on and around it.”   Students learn to “define weight as the force on an object due to a gravitational field.”   Mass is the amount of matter in a body whereas weight is the force due to gravity acting on a mass. Mass will not change where the acceleration due to gravity is different but the weight will change.        For example‚ bathroom weights are calibrated in kg‚ but actually measure

    call it Malfatti’s Problem. Tartaglia also had an avid interest in artillery‚ gunpowder‚ infantry‚ surveying equilibrium in balances‚ ballistics‚ and statics. He was a leader in the study of the motion of a projectile where he learned the maximum range of any given initial speed of a projectile is obtained with a firing elevation of . This would lead him to new ideas‚ methods‚ instruments‚ and ultimately firing tables to be used in warfare. Tartaglia suggested devices for finding height and distance

    Forensic Ballistics Most of us will have heard the term ballistics at some time or other-more often than not when we have been watching fictionalized accounts of police work on television or in the cinema. When you think of forensics you may think of something like “The Forensic Files”‚ “NCIS”‚ or even “Law and Order”. Although‚ ballistics is a part of forensics first we will look at forensics itself and how it came about. After getting the basics about the foundation in forensics we will look at

    musket with a lead ball could generally be accurate up to 75 yards‚ but with a rifle and a Minie ball‚ it was possible to have an effective range of 300 yards‚ where it was still accurate. Even more than that‚ the total firing range was was only 200 yards with the smoothbore musket‚ but ½ a mile with the rifle‚ about nine times the distance. With this increased range‚ it was much easier for the soldier to pick off

    Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

    Incompatibilism v. Compatibilism There are two prevailing incompatibilist views concerning free will‚ hard Determinism or Libertarianism. The former asserts that if determinism is true‚ then free will is nonexistent and humans are essentially robots following a path determined for us from our past and natural laws. The latter denies that determinism is true and thus appears to introduce randomness as an explanation to account for free will. Compatibilists claim that free will and determinism can

    World War Two but it is because of World War One’s major technological advancements that changed warfare into what it is today. World War One resulted in over thirtyeight million casualties because of new technology being used in the war like the long range kills of the artillery‚ the ability of literally mowing down forces with the machine gun along with other advancements‚ and the true terror of fighting from a trench. The Europeans expected a quick and mobile war but instead were treated with a long

    guns to harvest game. The two most commonly used firearms of hunters‚ are the rifle and the shotgun. Both the rifle and the shotgun are used for hunting‚ but the two have some major differences. The main differences between the two firearms are cost‚ range and the type of ammunition that each firearm uses. Most gun manufactures sell shotguns much cheaper than they sell rifles. Shotguns are not as complex internally‚ and have fewer parts than rifles. The simplicity of a shotgun also makes them easier

    guns‚ if used properly‚ are not any harm to anyone who follows and knows the rules of shooter safety. The first type of gun is the Rifle. This is the term used for a gun that has a rifled barrel (hence the name “rifle”) and only fires a single projectile per shot. It may have a clip that holds more than one cartridge‚ maybe for a follow-up shot if you miss a deer‚ or for easy and fun target shooting. There are many types of rifles‚ which is determined on how they load the cartridge into the chamber
