SUMMARY

The discussion centers on building a tennis ball launcher for a Science Games Day competition, with specific requirements to launch a ball over 10 meters and to a height of 1.5 meters. Participants suggest various designs, including a trebuchet, air cannon, and slingshot, while also noting the importance of adhering to size restrictions of 1x1x1 meter. A unique ski jump design is mentioned, although it may exceed the size limit. The user is encouraged to explore online resources for additional design inspiration.

PREREQUISITES
  • Understanding of basic physics principles related to projectile motion
  • Familiarity with mechanical design concepts
  • Knowledge of materials suitable for building launchers
  • Experience with safety protocols in experimental setups
NEXT STEPS
  • Research the mechanics of trebuchet design and its efficiency in launching
  • Explore air cannon construction techniques and materials
  • Investigate slingshot mechanics and optimal rubber band configurations
  • Look into safety measures for building and testing projectile launchers
USEFUL FOR

This discussion is beneficial for students participating in science competitions, educators looking for project ideas, and hobbyists interested in mechanical engineering and physics applications.

Hey guys, I am a year 10 student and I took part in a competition called the Science Games Day...One of the event stated that I need to build a tennis ball launcher that can launch over 10m and 1.5m in height...

There is also a lot of restrictions.

Can anyone help me with this like giving me a design that is good.I being dreaming to win this competition?

Thank you

We can't design it for you.

However, the document link shows several designs on the last graphic:

1) trebuchet

2) air cannon

3) slingshot

Not mentioned is a ski jump that would be unique but it might exceed the 1x1x1m size limitation.

You could also search online to see some examples and maybe search images too.
