We learn together to See It Big, Keep It Simple, and Make It Fun. How much electricity would I need in order to launch something based on the magnetic force only? My project is to launch a projectile into the air, and I am only going to use magnets. It is all about real world problem solving. For each angle, measure and record the range for three trials. Draw a conclusion about projectiles. We're getting it lined up and centered. Remember that our goal is to calculate the initial velocity of the ball, so we can then use the projectile motion equations to predict its path.

So now we're going to cut our launcher bar. Once constructed, is will perform reliably time after time. When you launched from the balcony, which angle achieved the greater range? And that'll leave enough space for the washer and the end of the bolt. Aside: Before gunpowder and guns - what sort of missile weapons did the military use? It allow the counterweight to drop in a straighter path. I've built a trebuchet before.

I can tell you the specifics about how to put it together if you wish. Could you predict where it will land? They can throw much farther then catapults. A small slingshot made out of surgical tubing might work, or as FredGarvin said a spring loaded or air powered cannon would be easy, tuneable and reliably repeatable as long as they were set up to lob, a catapault would have a better suited trajectory so the projectile would be less prone to roll after landing. And so we're going to make some design modifications in our next video. And we're tightening that down now. How much time did it take to reach F? Mathematicians are part of an ancient tradition of searching for patterns, conjecturing, and figuring out truths based on rigorous deduction.

You want to be careful doing that, so you don't cut yourself. Predicting the trajectory of a ball launched from the catapult requires an understanding of two fundamental physics concepts: projectile motion and conservation of energy. Students can be asked to predict the outcome of various experiments. Let me dig up a couple of pictures. I say potential is because you're using potential energy of a device to launch a projectile. So we're just drilling those holes and putting those wood screws in right now, tightening it all down.

Electromagnets do not easily change the amount of current flowing through them. This is the last cut we have to make on it. This will enable you to convert the distance you measure on your computer screen to real-world distance. This can be reduced somewhat by putting a capacitor across your switch pick one that can take hundreds, if not thousands, of volts. If you open the program, calculate your scale factor, and then make the video full-screen, your scale factor will no longer be valid.

The friction is also so great that it's hard for me to push the stopper in the same position each time. Catapults are good, but don't really take full advantage of the physics behind a giant falling mass. And now we're going to put our screws in on that side. All right, now we've got our piece, so we're just going to file that off very quickly to clean up the edges. One student Teaching Assistant, Nathan, took the lead in writing a specific proposal for a full set of launchers here at Donors Choose.

We also need to determine the potential energy stored in a spring. And so we've got the holes, and we're going to put our screws in, not going in all the way just yet, but most of the way. How are math and science related? When you pull the arm back, potential energy is stored in the rubber bands. That holds the bolt in place but still allows the aluminum to spin freely, you can see there. Let's take a look on the inside here. And we'll check to make sure that it all fits right and moves, and it does. By providing more projectile launchers we would be able both learn and experience more as we are able to complete the experiment in smaller groups; allowing for equal and more complete participation in the lab.

To measure x 0, you will have to measure the length of the rubber band while it is unstretched but flat. That means that the screws will be in the center of the bottom board we're screwing into. If the results match, you can conclude that your predictions and the assumptions you used to make them were valid under the circumstances of the test. You can look in the Bibliography or any high-school physics textbook for more information on these topics. And now we're going to put our eye screw in, and then we're going to insert the center pivot screw. Alternatively, students could be assessed by an alternative method, such as being asked for a written explanation of how this demonstration helped them understand projectile motion.

So we'll take our circular saw and trim that off. Think how you load a cannon, or a musket: can that be adapted for your launcher? The catapult kit also comes with two different balls ping-pong and Wiffle® and enables you to adjust the number of rubber bands. Anyone have any tips, suggestions on how I should go about this? I already based mine off an air compressor. You should have had a scale in your videos — we will use a 30-centimeter cm ruler as an example. You will need to read the instructions for the Tracker program and learn how to use it. So, what are the shapes and configurations of real-world projectiles? A try square like this works.

They then will devise an experiment to test their hypothesis. Now we're going to assemble all the different components. Working on your existing design: Have you tried altering the inside diameter inside the tube so it is a different diameter in different places? And then we have an eye screw here. Adequate time will be devoted to explore projectile motion, the scientific inquiry method, and learn and practice the connected math skills. What determines where it will land? What is the height of point A? A: First, make sure the box you are using for a castle wall isn't too big or heavy. Trebuchets are plenty accurate, even more over long distances.
