Ballistic pendulum purpose: to experimentally investigate the laws of conservation of energy and the conservation of linear momentum introduction. Name: partner(s): date: ballistic pendulum 1 purpose: primarily, this lab is included just because we like the word “ballistic. Experiment 19 the ballistic pendulum in this experiment you study the complex motion of a ballistic pendulum a ballistic pendulum is composed of a spring-gun which fires a metal ball, a physical pendulum with a bob which traps the metal ball, and a rack capable of measuring the maximum swing of the pendulum. Purpose to utilize two different methods of determining the initial velocity of a fired ball, namely a ballistic pendulum and treating the ball as a projectile, and then compare these two calculated values. 3ballistic pendulum machine 4projectile (metal ball) 5triple-beam balance introduction the ballistic pendulum is a classic method for determining the velocity of a projectile origi-nally, it was used to determine the muzzle velocity of rearms it is also a good demonstration of many basic principles of physics. Learning objective: conservation of momentum m1 v1 = m2 v2 mass of the projectile times speed of the projectile before impact = mass of the pendulum times speed of pendulum+projectile after impact the ballistic pendulum was invented in 1742 by english mathematician benjamin robins. In this experiment, energy conservation and momentum conservation will be investigated with the ballistic pendulum 42 introduction one of the basic underlying principles in all of physics is the concept that the total energy of a system is always conserved.
Worked example 75: ballistic pendulum question: a bullet of mass strikes a pendulum bob of mass horizontally with speed , and then becomes embedded in the bob the bob is initially at rest, and is suspended by a stiff rod of length and negligible mass the bob is free to rotate in the vertical direction. Explains the physics behind the basic ballistic pendulum problem for a complete index of these videos visit here's a fun gi. Product description trajectory path it has a nylon pendulumthe base and the pendulum have. Experiment 8 ballistic pendulum conservation of linear momentum (before and immediately after the collision) conservation of energy (during the swing of the pendulum. A ballistic pendulum is a device for measuring a bullet's momentum, from which it is possible to calculate the velocity and kinetic energy ballistic pendulums have been largely rendered obsolete by modern chronographs, which allow direct measurement of the projectile velocity.
How does a ballistic pendulum give information about a bullet or ball here is a derivation of the classic introductory physics problem. Ballistic pendulum) originally invented for determining the speed of a bullet in our version, a steel ball is shot from a spring-powered projectile launcher and. A student researched lab analysis exploring the ballistic pendulum the goal was to determine the velocity of a ball as it is shot from a launcher.
Chapter 4 energy andmomentum - ballistic pendulum 41 purpose in this experiment, energy conservation and momentum conservation will be investigated. Ballistic pendulum a bullet of mass m is fired at a block of mass m hanging from a string the bullet embeds itself in the block this is an inelastic collision, in contrast to an elastic collision where energy is conserved. The principle of conservation of momentum (which states that the momentum of the objects before they collide will be equal to the momentum of the objects after they collide), and the law of conservation of energy (which states that the kinetic energy at the moment of collision will be equal to the potential energy at the top of the pendulum. In last week’s recitation question (scroll down two posts if you don’t know what i’m talking about), we examined a bullet (mass m) hitting a block (mass m) hanging from a string (length l) at the end i ask you what would have happened if there was an inelastic collision and the bullet was.
Ballistic pendulum physics 211 lab this example would be a two stage combo problem the 1 st stage would be a collision between the bullet and the block. The ballistic pendulum lab is a classic experiment that determines conservation of energy and angular momentum. Physics 31210 spring 2006 experiment 5 5-3 ymax v y o figure 2 2 to measure y properly, we need to locate the center of mass of the ball/pendulum. 1 of 5 p28 lab #5 summer 2004 stanford physics dept ballistic pendulum gregory s romine.
A ballistic pendulum is a device used to measure the speed of a bullet a bullet of mass m is fired at a block of wood (mass m) hanging from a string the bullet embeds itself in the block, and causes the combined block plus bullet system to.
The ballistic pendulum, invented in 1742 by english mathematician benjamin robins, revolutionized the science of ballistics as it provided the first way to accurately measure the velocity of a bullet. The purpose in this lab is to use a ballistic pendulum to find its initial velocity of a projectile using the conservation of momentum as well as the conservation of energy introduction: we will be shooting a steel ball into the bob of a pendulum at a certain height which is where the bob will get stuck at. 1 ballistic pendulum and conservation of momentum formal report for lab #8, physics 4a by bryan campbell 10 abstract in this paper, we aim to validate one the most important and frequently used tools of. 2 locate the center of mass of the ball + pendulum system 3 measure the mass of the ball mb with the pan balance the mass of the pendulum mp is marked on the pendulum 4 prepare the gun for firing by placing ball on gun rod and cocking the gun 5 place the pendulum at rest in its vertical position 6 pull the gun trigger 7 measure the height ‘h. 1 experiment 5 the ballistic pendulum preparation prepare for this week's quiz by doing the usual review, reading the experiment, and reading the. The ballistic pendulum (approx 90min) (12/16/15) introduction in this lab we will use conservation of energy and momentum to determine the velocity of a projectile fired into a pendulum and compare it to the velocity determined by looking at the trajectory of the projectile when it is launched across the room. Purpose: to use the ballistic pendulum to determine the innitial velocity of a projectile using conservation of momentum and conservation of energy equipment: ballistic pendulum, carbon paper, meter stick, clamp box, triple beam balance, plumb.
Answer to the ballistic pendulum used to be a common tool for the determination of the muzzle velocity of bullets as a measure of. A ballistic pendulum measures a bullet's/ball's momentum, which can be calculated to find velocity and kinetic energy you would have to measure a couple of things before being able to calculate the kinetic energy first, measure the mass ball/bullet (mass 1) and the mass of the catcher (mass2.
