Has anyone try measuring force? I heard that there is a Ecuation that can do so I think it's

force = mass x acceleration. Sorry if this has been posted before.

A 50 gram stone travling at 100 feet per second gives about 1 newton.

B_S_G - why all this stuff?

I applaud your enthusiasm, but you need to learn a little science - I guess you should be getting this kind of stuff at school, right? First tip is not to mix up your units, second is to learn what these concepts like force mean.

You can still read a book - that is where I learnt this stuff when I was younger than you are now.

I make rockets and cannons and stuff like that :)

I agree that it is good to have such enthusiasm for physics, but I believe that you won't do yourself much, if any, good if you aren't very sure what you're putting into and taking out of an equation. For instance, check again; 100 feet per second is a unit of velocity, not acceleration, and the unit in your site of reference is actually feet per second^2.

That said, if this is still exciting for you, I strongly encourage you to get your hands on a high-school physics book or perhaps, if you can find something acceptable, some internet resources for learning physics. Enthusiasm for a particular subject can be a powerful thing and a great opportunity to learn.
