Science Buddies: "Ask an Expert"

Hi,

My child has a project that they have to do that encompasses all of Newton's three Laws of Motion. He wants to construct a windmill showing this, nothing too advanced, child is in 6th grade. We are not exactly sure where to begin and we don't know if this idea would work to encompass all three of Newton's Laws of Motion. Also, he has to figure out what the Inertia, Average speed, (Net, Magnetic, Gravitational, and Contact) forces, (Negative, Positive, Centripetal) acceleration, etc.

He also has to have: two problems determine speed when distance and time are given
two problems determining distance when speed and time are given
two problems determine time when speed and distance are given

If you happen to have any other ideas that might fit this project better please all ideas are welcomed. Thank you for your time and help!
Best Regards,

Hi,

For a beginner project like this about Newton's Laws, I would suggest working with something that moves in a straight line instead of something that rotates (like a windmill). It's a little easier to understand and do the math. We have a lot of "car" projects that work pretty well with Newton's laws and things like calculating speed. They might be a good place to start - you can find them linked in this blog post:

Hope that helps, write back if you have more questions!

Hi!
Awesome project idea!
Though we're happy to help you here, I suggest you post your question in the Physical Science forum. That way, experts who are more knowledgeable about this kind of subject can help you out, even though the other mentor who helped you did an awesome job!

Just a suggestion!

Stay nerdy,
