Introduction Projectile motion occurs when an object in a two dimensional plane experience sees motion only due to gravity. Cinematic equations can be used to describe the common .NET of projectile motion. This allows us to analyze the motion. In this lab measurements will b e taken to determine the initial velocity of objects experiencing projectile motion. This w ill first be done for objects that are starting from a set elevation above the landing area. Then the initial velocity will be found for objects that are launched from the floor at an angle to a land inning area of the name elevation.

This will teach the concepts of projectile motion for objects t hat start from horizontal and objects that start at angles. Familiarity with cinematic sequoia ins will be increased through there repeated use in this lab. Also, this lab will create an understand ding between the measure of the initial angle, and the distance a projectile travels in the x direct Zion. Because the same instrument will be used to fire the projectile each time, and the projectile e used will be constant, the initial velocity will likely be the same for all situations tested.

Methods The pendulum of a ballistic pendulum was moved back so that it would not GE t in the way of the firing mechanism. This became the instrument that would be used to fire the projectile for this lab. This was initially place on a table where it would be fire d from initially. A long piece of bulletin board paper was spread across the floor. The projects el was test fired by pulling the piston back one notch and then pushing down on the trigger. After r the position of the test fire was noted the paper was moved accordingly.

A table was laid on its s did to act as a cockatoos for the projectile. The projectile was then fired five times to the pap re, and a mark was made where the projectile landed on the paper. The horizontal distance from the end of the firing mechanism to the mark on the paper was measured. Also, the vertical distant CE from the end of the firing mechanism to the floor was measured. The average Of the horizon al distances was found, and will be used for calculations. After the distances from a horizontal start were measured the firing mechanism m was moved to the floor, and the paper was turned over.

Text books were used to prop the end of the firing mechanism up to an angle of twenty degrees. This angle was verified us inning a protractor. The projectile was fired from this position three times. Each time the landing spot was marked and the horizontal distance measured. The average of these measurements was recorded. This was repeated for angles of thirty degrees, forty degrees, fortifier degrees, fit y degrees, sixty degrees, and seventy degrees. Rest Its The value of the initial velocity for each trial was found to be relatively constant NT.
