As the height of the bullet's release increases the the time …show more content… The theoretical and the experimental ranges were almost identical, and in some cases they were Sources of error: The first source of error was the toy gun's bullet were not perfectly a cylinder.
The toy gun was steadily held in my hand. Time graph, the time represented the corresponding heights of the Horizontal Distance vs Height graph. Include the derivation in your lab report.
Projectile motion experiments are a staple of introductory physics laboratories, and generally. In the beginning, it would works sometimes, but not always.Everything is affected by gravity, but it profoundly alters the motion of objects that are thrown or shot upward. This would cause some twisting and turning of the bullet since the rips would collect air and make the bullet therefore move around sort of like air pockets. Questions: What is the shape of the actual path travelled by a projectile? The only reason our group concluded to be the source of the short fall of our ball was that we had the wrong initial velocity of the ball. How closely does an actual projectile's results follow the theoretical predicted results? It would have been wiser to take a shot at 45 degrees then calculate the velocities rather than have a bunch of random ones which gave too much uncertainty. Your answers and initial your lab report. A report summary should be generated like the one in Figure 7. Since the bullets we made out of plastic foam there some ripped edges. Predicting and Verifying the Range and Total Time-of-Flight Use the equations you derived in the Pre-lab Assignment to calculate the expected range and time-of-flight using your best estimate of the average initial velocity for the short range setting, and the launch angle. A metre stick was used to determine the horizontal range for the experiment. The toy gun was steadily held in my hand. Next we do the math and place a penny where the steel marble should land.
The clamp will secure the launcher so recoil is negligible. Everything is affected by gravity, but it profoundly alters the motion of objects that are thrown or shot upward. As stated earlier a metre stick was used to determine the horizontal range for the experiment.There can be ways though to fix these sources of errors. Please discuss with your partners. Gravity causes change in the vertical velocity of the projectile. Figure 2 To predict the range of the projectile when it is shot off a table at some angle above the horizontal, it is necessary first to determine the initial speed muzzle velocity of the ball. Physics lab report-motion. This would cause some twisting and turning of the bullet since the rips would collect air and make. As the height was increased, the range was also higher. The graphs were very similar due to the horizontal distance cm being constant on the y- axis of the graph. Introduction A toy company is now making an instructional videotape on how to predict the position. Department of Physics. Since the bullets we made out of plastic foam there some ripped edges. Since the bullets we made out of plastic foam there some ripped edges. This means that is a curvy shape due to the bullet being launched in the air making curve go up and the earth's gravity pulling it down making curve go down. Firing height and firing angle is messy, and is given in the lab manual.
The bounce was easily dampened by placing two or three sheets of paper under the end of the ramp.
