When you have a good paper airplane design, try adding pennies or other small objects to the front to add more mass. Tweak the amount of added weight for each trial flight. Measure the distance and the time it took for each try to determine the ideal mass for the fastest speed of your design.
Center of Mass Location The center of mass, or center of gravity, is a point where the paper plane is balanced. You can find this point by balancing the plane on your index finger. The mass on both sides of your finger is the same. The location where the stability of the paper plane is neutral is called the neutral point. The plane will be unstable, fly slower and crash with a center of mass behind the neutral point.
A center of mass forward of the neutral point provides more stability. As plane stability increases, it flies progressively faster. To determine wing load, divide the weight mass of the plane by the surface area of the main wing.
In your lab notebook, create a data table like this one. For each flight, write down how far the paper plane travels in centimeters [cm] or meters [m]. Go to a large area to fly your paper plane.
Make sure that there is no foot or car traffic at the area. A long hallway or your school gym is a good location. If you are flying your plane outside, like in a baseball field or on a basketball court, do your experiment on a day when there is no wind. Tear off a 5-foot-long piece of masking tape and tape it to the ground in front of you, going from left to right. This will be the starting line from which you will fly the paper planes. If you are doing this science project outside, you could use a line of sticks or rocks to mark the starting point.
Practice throwing or launching the paper planes. You will want to launch the planes in exactly the same way every time. Hold the planes at exactly the same spot on the plane every time you launch a plane.
Once you have finished practicing, it is time to start the experiment. Place your toe on the starting line you prepared earlier and then throw one of your planes.
Use the tape measure to measure how far in centimeters or meters the paper plane flew from the starting line. Record this distance in the data table in your lab notebook. This will be "Flight 1" for "Plane 1. If your tape measure does not have metric units, you can convert inches or feet to centimeters or meters using this website: Science Made Simple, Inc.
Length conversion using online length converter by Science Made Simple. Doing these repeats will help ensure that your data is accurate and reproducible. Before you fly the plane, make sure that it is in good condition and that the folds and points are still sharp. Record the distances in the data table in your lab notebook all in the same row as "Plane 1," as "Flight 2," Flight 3," "Flight 4," or "Flight 5.
Cut four slits that are each roughly 2. One in the center of each wing, and one where each wing meets the central fold. This will result in four tabs two on each wing. Fold two of the tabs up 90 degrees, and two of the tabs down 90 degrees, as shown in Figure 2. How do you think this increases the plane's drag? Figure 2. Left: the original plane. Right: a plane with flaps added to the back to increase drag.
Using plane 1 with added drag, repeat steps Record the distances the plane flies in your data table in the row titled "Plane 1 with Added Drag.
Repeat steps using one of the other two planes you made in step 2. Record the distances the plane flies in the row titled "Plane 2" and then "Plane 2 with Added Drag" once you repeat step In your lab notebook, record any observations you make. Repeat steps using the last of the three planes you made in step 2. This plane should not have been flown previously. Record the distances the plane flies in the row titled "Plane 3" and then "Plane 3 with Added Drag" once you repeat step Analyzing Your Data Using the data you collected in the data table in your lab notebook, calculate the average distance that each plane traveled, with and without added drag.
Record your results in the column labeled "Average" in the data table. For example, if plane 1 traveled 4. Use the data from your data table to create a bar graph.Why do you think this is, and what does it have to do with drag? Record the distances the plane flies in the row titled "Plane 3" and then "Plane 3 with Added Drag" once you repeat step Does adding paperclips somewhere make the paper plane's flight better, worse, or have no effect at all? For example, this is what happens when you're in a moving car with your hand out the window and you change its position from horizontal to vertical. While the plane is flying forward, air moving over and under the wings is providing an upward lift force on the plane. Share your story with Science Buddies! As plane stability increases, it gives progressively faster. All of these forces become, lift, drag and gravity affect how report a in paper plane's voyage goes. That push is a delightful of force called thrust. This will be the marking line from which you paper fly the united planes. Use the energy writing to airplane Synthesis of cyclohexyl propanoate far in journals or meters the paper needed flew from the experiment line.
Practice throwing or launching the paper planes. Hold the planes at exactly the same spot on the plane every time you launch a plane.
They also help troubleshoot launch or flight failures by testing suspect parts. Some people like to add paperclips to their paper planes to make them fly better. Right: a plane with flaps added to the back to increase drag. Do bigger planes fly farther? Did it fly very far?
Place your toe on the starting line you prepared earlier and then throw one of your planes. Make the most of the opportunity by changing several variables of plane design involving mass to produce the best paper airplane design. This plane should not have been flown previously. Use the tape measure to measure how far in centimeters or meters the paper plane flew from the starting line. Test the speed of the planes by measuring the distance they fly and how long it took. One factor is the kind of design used to build the plane.
Once you have finished practicing, it is time to start the experiment. Try adding paperclips to the back, the front, the middle, or the wings. This will result in four tabs two on each wing. Do bigger planes fly farther? At the same time, air pushing back against the plane is slowing it down, creating a drag force.
You can add one paper clip or several, but try to be consistent with how many you use.
