Physics extended essay ballistics

Simply defined, Yaw is a deviation of a forward moving aerodynamic object from its longitudinal axis. The velocity of the airgun pellet was found to be much more consistent for airgun B. We can also use the velocity of pellet u calculated using the maximum height h, to predict Physics extended essay ballistics velocity of the ballistic pendulum just after impact, and compare it with the actual velocity measured directly using TRACKER.

There are devices called chronographs that gun hobbyists use to measure bullet velocities, but they are prety expensive! Rifle shooters, on the other hand, fire longer projectiles that require up to 48 feet to stabilize. That will allow you to approximate the ball's velocity since the potential energy stored on the spring goes into kinetic energy of the ball plus of course loss due to friction and the kinetic energy of the plunger.

Well, you will need to decide on what kind of ball you want to investigate.

External Ballistics Part I – Physics, Projectiles and Transitional Ballistics

Open Source Physics, 1 Jan. Therefore, handgun cartridges and short-range rifle cartridges do not benefit from a boattail projectile. Therefore, although the firearm appears level, the projectile exits the bore at a slight upward angle.

Shooting at modelling clay bull's eye to measure accuracy and precision of the gun Airgun B showed close grouping of pellets on the target as shown above. Sheet 3 at a distance of 2. Anil for providing the apparatus required to set up the experiment. Science journalism We invite links to all websites, but article and blog post submissions require proper sourcing from the literature or mainstream scientific journalism.

When writing an extended essay, it is crucial to keep in mind all the existing relevant theories and keep all the facts you refer to substantiated. Comparison of measured and predicted maximum velocities of ballistic pendulum for airgun B Posts should be pertinent and generate a discussion about physics.

Inhalt pflichtenheft beispiel essay socrates and plato compare and contrast essays. We can also measure the initial velocity of the ballistic pendulum just after the pellet gets embedded into it, by using the TRACKER software.

You can also see this in slow-motion replays of long football passes. Ballistic pendulum setup being used to measure the velocity of airgun B which generated more consistent velocities Careers questions Questions regarding job opportunities and working as a physicist have a dedicated weekly Careers and Education thread and should be posted there.

So this method to measure the speed of the pellet was a failure A ping pong ball would be most convenient but they are smooth, so you probably would need to roughen the surface up, perhaps with sandpaper. Comparison of measured and predicted maximum velocities of ballistic pendulum for airgun A The accuracy and precision of the airgun A is very poor beyond 2 m.

Even though we cannot observe the forces acting on a projectile the moment it leaves the muzzle, we know those forces significantly affect its actual path.

This leads to really interesting optical properties, and presumably affects the conductivity too. Retrieved March 6,from http: The short length of pistol projectiles allow them to stabilize quickly and within just a few feet.

Incidentally, if you are not afraid of chemistry then reaction mechanism is a field where a very brilliant and well-read beginner with only intelligence and imagination and a reasonably good lab as his weapons can do some truly original and exciting work that may not turn out to be merely "the transfer of bones from one graveyard to another".

The maximum height reached by the modelling clay ball with the pellet embedded in it were measured using TRACKER software by analysing the videos of the motion of the ballistic pendulum.

Another source of error in calculating pellet velocity could be due to air resistance slowing down the ballistic pendulum and hence reducing the maximum height achieved by it.

I would favor the ping ping ball because you can do the work indoors and thus rule out the effect of wind. This leading edge affects the amount of drag air resistance. The holes have spread apart so much that they are almost going out of the page.

Incidentally, if you are not afraid of chemistry then reaction mechanism is a field where a very brilliant and well-read beginner with only intelligence and imagination and a reasonably good lab as his weapons can do some truly original and exciting work that may not turn out to be merely "the transfer of bones from one graveyard to another".

The gun may not be fired perfectly horizontally in every trial. Set up of graph sheets at 1 m intervals to track the spread of the trajectory of the air gun pellets with distance travelled. This is the somewhat longer surface area along the length of the projectile that presses against the inside of the bore.

Tracker screenshot- measuring the maximum height reached by the ballistic pendulum, and maximum velocity attained by the ballistic pendulum immediately after being penetrated by the pellet.

In this process, the nose of the projectile varies in a helical motion until it is dampened to stabilized ballistic flight, which is nutation. The first was to attach the gun to the pendulum, and measure the recoil.Ballistics The motion of a projectile, from the instant of firing until impact at the target, is divided into three distinct phases: (1) interior ballistics, which treats of the motion of a projectile while it is still in the gun; (2) exterior ballistics, which considers the motion of the projectile from the time it emerges from the gun until it reaches the target; and (3).

The extended essay I am submitting is my own work (apart from gUidance allowed by the International Baccalaureate) I have acknowledged each use of the words, graphics or ideas of another person.

whether written, oral or physics behind the process of using rockets to launch the space shuttle. Rockets apply. Basically the extended essay is a piece of independent research done during the course of IB. I'm planning to do a physics EE, but now it's mid April and I still failed to find a simple yet specific topic to do reasearch on.

Transitional Ballistics, Yaw, Precession and Nutation: Simply defined, Yaw is a deviation of a forward moving aerodynamic object from its longitudinal axis. Precession is an angular force applied to a rotating object caused by its torque.
