In this lab study. the scope a foam disc launcher shooting was tested by changing the angle of flight followed by mensurating the scope. The scope that the froth disc went was measured in centimetres and multiple shootings were taken at each angle and so averaged. Galileo was the first individual who accurately described projectile gesture. Because of the drawings of Niccolo Tartaglia. Galileo realized that a missile followed a curved way which is called a parabola. 1 It was subsequently found out by Galileo that the parabola has an exact mathematical form. Besides. he stated that a missile was acted upon by two forces. perpendicular and horizontal. The perpendicular force was from gravitation. which pulled it to Earth at 9. 8 m/s. That is why a parabola is a precise mathematical equation. 2 Observations were conducted before the experiment was started. First. observations were made on two racquetballs. one being pushed from a tabular array. and another being dropped vertically to the floor. Equally shortly as the one pushed across the tabular array went off the border. the other was dropped vertically. They both hit the land at the same clip. because gravity’s force on them was the same. A racquetball was besides observed by fliping it with the same speed at different angles between two people. At a 0? angle. it went horizontally until the terminal of its flight when it lost its impulse and started to swerve toward the land. In fact. even the froth discs were observed. Since there was no air current in the research lab. it made for a stable environment. But. when the disc was launched at a 45? angle. its rotary motion made it swerve backwards. As good. in this experiment an on-line game. The Balloon Game . was played where the consequence of angle and speed were studied in footings of how they affected parabolic gesture. 3 In this game. it was observed that the scope of the missile increased up to 45 grades but so decreased beyond 45 grades. with 45 grades being optimum.

The disc launcher was set a metre of the land and was shot three times each at a 0? . 20? . 45? . 70? . and 90? angles. It was hypothesized that the greatest distance would be from a 0? angle. but the greatest distance came from when the launcher was shot at 45 grades. The norm of the three shooting distances was taken and was used to do a graph which made a parabolic arch on a graph. The distance that the froth discs went was measured in centimetres and was rounded to the nearest centimetre. Materials and Method Shooting Disc Gun Meter Stick Protractor Three phonograph record Tablet PC 1. Load a shot phonograph record gun with three phonograph records. 2. Put the metre stick on top of the land ( this is where the missiles will be fired from ) . 3. Put up the shot phonograph record gun so that it is on top of the metre stick. 4. With the protractor. step the grade that the hiting phonograph record gun is hiting from. 5. First set up the protractor at a zero grade angle ( indicating directly out ) . and so shoot the three phonograph record from this angle. 6. Measure the distance all three of the phonograph record traveled and happen the mean. Record this for the mean distance for a missile being shot at zero grades. 7. Repeat stairss # 5 and # 6. nevertheless each clip. vary the angle. The five angles that will be tested out in this process are: 0 grades. 20 grades. 45 grades. 70 grades. and 90 grades. 8. Make a tabular array and so chart this information utilizing Microsoft Excel. Joselyn J. Todd. Example Lab. 9/12/2006
