My Catapult Assignment: Popsicle Sticks And The Elastic Band

246 Words1 Page

Catapult Assignment How it worked:
My catapult functioned by using built up tension in the 2 vertical popsicle sticks and the elastic band wrapped around the 2 popsicle sticks.

The forward momentum is created by using the potential energy in the popsicle sticks and the elastic band; so when it is released, all the potential energy, becomes mechanical energy. My catapult is a slingshot style design.

If I were to build my catapult again, I would probably add a calibration device, because when the catapult is fired it does not always shoot the same way, as the elastic is not restricted in any way.

I think my catapult was successful because 3 times out of 5 I was able to get near the hole on the target. The catapult also shoots much quicker

  • Ball Bounces Lab Report

    1007 Words  | 5 Pages

    TASK: When a ball is dropped from a height, it loses some of its energy and each bounce gets shorter. Your investigation will determine the effect of original drop height on bounce height. From this, energy loss can be calculated between bounces. As different groups will be using different balls, you will be able to compare energy loss with different balls. You are required to present your findings in a lab report format, which has been detailed below.

  • The Engineering Of A Trebuchet Essay

    748 Words  | 3 Pages

    The parts of a trebuchet, work with Newton’s first three laws; to state simply, anything at rest stays at rest while anything in motion stays in motion unless something acts upon them. This law is used as gravity causes the counterweight to free fall, the momentum of this object builds up potential energy as the arm rotates around the fulcrum. Then, Newton’s Third law as the counterweight falls, the sling (on the other end of the beam) rotates up, then the potential energy is turned into kinetic energy as the projectile is released from the sling and

    The golf ball would fly down a race track and then set off another mousetrap. Next, the mousetrap would pull a string out of a book which would close the book on top of scissors. Finally, the scissors would cut a string which is holding up a dumbbell and the dumbbell would crack the egg which is sitting in a bowl. This is the project we decided to design in order to crack our egg.

  • How Did A Catapult Build Springy?

    In this project, David and Goliath, assigned by Mr. Kumz, a catapult was built, Springy.. In this experiment three different variables were tested; angle of launch, stretch length, and the skittle position. The angle of the launch had three measurements: zero and forty-five degrees. The stretch length measurement were 2, 3, 4, 5, 6, 7, and 8 centimeters, while the skittle position was flat and on its side. Springy’s most effective launch was at a zero degree and with a stretch length of five centimeters.

    For this experiment, I used the online Mass & Springs PhET simulator to perform the experiment. First, I positioned the ruler so that 0 was on the line at which the end of the spring was at rest. Then, I put a 50g weight on the end of the spring and let the spring come to rest. After that, I pulled the spring down 10cm and released. I recorded the point at which the spring’s rebound stopped.

    Lab Group: Thomas Echelberger, Austin Brown, Erik Holden, and Josh Peeples Introduction: For this lab we had to construct a projectiles launcher that would shoot ping pong balls at different distances. At the beginning of the project we though of doing a generic catapult made of popsicle sticks. But we wanted to go above and beyond. So we decided to make a launcher that would use air pressure to power the ping pong ball.

    Could you imagine what it would be like if you go to your little cousin’s birthday party, and he or she get upset because there were no balloons? If legislators ban balloons, this imagination could become reality. There is a controversial topic going around that asks if it would be best if balloons were banned in the United States. This controversy was discussed in a video, “California Aims to Ban Metallic Balloons to Reduce Power Outages,” the editorial, “Parties Can Be Fun Without Balloons,” by Natalie Romero, and the other editorial, “Balloons Bring Joy to Millions,” by Theo Lewis. While there were similarities among the sources, there were also many differences as well.

  • Physics Of A Lacrosse Essay

    Physics Project For my Physics Project I decided to learn about the physics behind cradling a Lacrosse ball. I also wanted to see what happened when I changed the size, shape, and weight of what I was cradling and how that would affect the result of the level of difficulty and my level of performance. My hypothesis was that cradling objects that were the same size but lighter than a lacrosse ball would make it the easiest to learn how to cradle and improve my performance the most efficiently. For my baseline test I cradled with you guessed it a lacrosse ball, I tested how much effort it took me to cradle with my dominant hand and then how easy it was to switch to my non-dominant. (This is something that you have to be able to do in Lacrosse

    The hypothesis of the badminton birdie experiment was accepted. When a little mass is added to a badminton birdie, and hardly any weight, the number of times it goes over the net, when you hit, it will increase. The Sportime and Referee badminton birdie brands were the two different brands used in this experiment. When mass was not added to the badminton birdie, the graph shows the Referee brand has more hits. The Referee brand was still in the lead at two grams added, but at 4 grams the brands were tied.

    During the double-ball drop experiment, the top ball moved up while the bottom ball moved down. During the initial drop, the balls are released and fall to the ground with the same acceleration. However, the instant that the bottom ball hits the ground, the two balls experience the first collision. In order to conserve energy and momentum during the elastic collision, the collision causes the top ball to bounce upward with the same speed it had before hitting

    The next 20 arrows were similar: my shots landed reasonably well into the huge targets, but I would need a lot more practice before the arrows landed in the bulls-eyes with any sort of regularity. After 5 such target sessions, I took a moment to dash around in the gimbal elliptical machine for ten minutes, then returned to the target field for accuracy training, taking 6 seconds on each arrow rather than the three I spent on each arrow earlier. The arrows still landed away from the bullseyes with frustrating regularity, but it was an improvement over 6 months ago, when I couldn't hit the target
