I would probably make both the spring force and the stop angle adjustable, and then use lots of practice shots to calibrate both adjustments to give me the best repeatability.
Putting some targets on walls is an interesting twist. Have you thought about how best to handle those?
To build a catapult, you will need to gather materials such as wood, rubber bands, and a spoon. Follow step-by-step instructions or watch tutorials online for guidance. Make sure to test your catapult before using it for your project to ensure it works properly.
The best design for a catapult depends on its purpose. Some factors to consider are the distance you want to launch an object, the weight of the object, and the materials available. Experiment with different designs and see which one works best for your project.
To improve the accuracy of your catapult, you can make adjustments to the angle and tension of the rubber bands, as well as the weight and shape of the object being launched. You can also add stabilizing features such as a base or support structure.
When using a catapult, always wear protective gear such as safety glasses and gloves. Make sure to use caution and follow all safety guidelines when launching objects. Keep bystanders at a safe distance and never aim the catapult at people, animals, or fragile objects.
To make your catapult stand out for your project presentation, you can add decorative elements such as paint or decals. You can also include interesting facts or historical information about catapults in your presentation. A working demonstration of your catapult can also impress the audience.
