Devise a "launcher" for the ball from a ruler or book - anything with a smooth groove in it that the ball can roll down. Find a starting point on the launcher that gives the ball a reasonable velocity. Place 2 pieces of tape cm apart on the lab table in the path of the ball.

Amatol - An explosive mixture Projectile lab ammonium nitrate and TNT. Ammunition Identification Ammunition is identified by markings and color-coding on the items themselves, the containers, and the packing boxes.

This appendix gives a basic explanation of markings and color-coding. Because color-coding is a more ready means of identification, it is given greater emphasis here. AP - Armor Piercing. Projectile for use against heavily armored targets. Very little explosive within the shell, as it must be almost solid in order to penetrate through armor plate.

Most AP shells have a cap fitted over the nose which is intended to exert a high initial force on the face of the armor.

In addition, a ballistic cap is usually fitted over the AP Cap to provide a more streamlined shape for better aerodynamic characteristics. Arrow Shell - A fin-stabilized HE projectile. Propellant bags were manufactured from a special coarse silk known as "shallon" or "cartridge cloth.

Rayon bags replaced silk ones in the USN after a serious propellant fire aboard USS South Dakota BB in was traced to a spark generated when a bag was removed from its metallic container.

Using the Interactive

Ballistic Cap - Often called a "windshield," this is a covering on the nose of a projectile which is intended to provide a more streamlined shape for better aerodynamic - ballistic - characteristics. Back to Top Ballistic Coefficient - Measure of the ability of a projectile to overcome air resistance.

Sectional density is calculated from the mass M of the projectile divided by the square of its diameter. The value of F decreases with as the pointedness of the projectile increases. A projectile shaped like a sphere would have the highest F value while one in the shape of a long needle would have the lowest F value.

Ballistic Conditions - Conditions which affect the motion of a projectile in the bore and through the atmosphere, including muzzle velocity, weight of projectile, size and shape of projectile, rotation of the earth, density of the air, elasticity of the air and the wind.

Ballistic Curve - Actual path or trajectory of a projectile. Ballistic Density - Computed constant air density that would have the same total effect on a projectile during its flight as the varying densities actually encountered.

Ballistic Efficiency - Ability of a projectile to overcome the resistance of the air. Ballistic efficiency depends chiefly on the weight, diameter and shape of the projectile. Ballistic Length or Head Length - The length of the projectile's nose.

Ballistic Limit - Velocity at which a given type of projectile will perforate a given thickness and type of armor plate at a specified obliquity. Ballistics, Internal, Intermediate, External and Terminal - Internal Ballistics is the study of what the projectile does from the moment of firing up until it leaves the muzzle of the weapon.

Intermediate Ballistics is the study of the projectile between the time it exits the muzzle until it overtakes the muzzle shock waves and enters normal atmosphere. External Ballistics is the study of what the projectile does as it travels from the end of the intermediate stage to the target.

Terminal Ballistics is the study of what the projectile does as it strikes the target. Balloting - The bounding from side to side of a projectile in the bore of a gun. Base - The after end of the projectile, usually described as that portion between the driving bands and the bottom of the projectile.

Base Bleed - This is a unit on the base of a projectile that generates a gas, something like a tracer. What this does is fill in the vacuum that is created behind a rapidly moving projectile and thus greatly reduces the amount of drag acting on the projectile.

The gas also acts like a long tail, making the projectile more stable in flight.

The end result of these actions is an increase in range and accuracy. Base Cover - A metal cover that is crimped, caulked or welded to the base of a projectile. This cover prevents the propellant gasses from coming in contact with the explosive filler of the projectile through possible flaws in the metal of the base.

Base Plug - A removable seal in the base of a shell which holds in the explosive filler. Belt, Ammunition - Multiple rounds of ammunition that are held together by a strip of fabric or metal. Used most often for feeding ammunition to automatic weapons.I was pretty excited to test this new bad boy of the chronograph world out.

So I asked Rhian aka “BignGreen” to come along and help. I mean if a guy is going . A railgun is a device that uses electromagnetic force to launch high velocity projectiles, by means of a sliding armature that is accelerated along a pair of conductive rails.

Projectile Lab – student You will shoot a projectile across the room using a rubber band and calculate how far it flies. Part 1 – Preliminary Measurements. Calculating Barrel Pressure and Projectile Velocity in Gun Systems The following information was derived and provided by Close Focus Research (CFR) for those who are interested in Calculating Barrel Pressure and Projectile Velocity in Gun Systems.. Keep in mind that the results rendered by the methods below are based purely on Math and Physics. Experiment 5 - Air Track.

It is typically constructed as a weapon, and the projectile normally does not contain explosives, relying on the projectile's high speed to inflict damage. A coilgun or Gauss rifle is a type of projectile accelerator consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity.

In almost all coilgun configurations, the coils and the gun barrel are arranged on a common axis. It is not a rifle as the barrel is not rifled. The projectile motion experiment applies a working knowledge of kinematics for Launcher, projectile, Smart Timer, Time-of-Flight Pad, 2Table Clamps with rods, Failure to do so will find you expelled from the lab room.

It is. Let’s solve the example of a quadratic equation involving maximums and minimums for projectile motion given above: A ball is thrown directly upward from an initial height of feet with an initial velocity of 96 feet per second.

After how many seconds will the ball reach its maximum height? And, what is the maximum height? Experiment 5 - Air Track. Home • NEWS • Demos • Physics Mail • Physics Forum.. 10, 16, 17, 25, 27, 28, 29 • Search • iPhysics • MicroLabs a, & b.
