i have to design an experiment... as far as it is now, all of my ideas seem to be ridiculous and too complicated...
please... help me....

hi there... thanks anyway for answering... i meant the experiment should be designed so the data gathered is quantitative, not qualitative....

I don't think you can "prove" newton's second law.
You can verify it or demonstrate it.
With balloon, string & straw, you can't do much with F=ma quantitatively, unless you could measure the force of the exiting air, and the mass of the balloon and whatever air is in it.

Put the straw into ballon( in order to blow some air), then tie it up with string, blow some air into the ballon through the straw. The air in the ballon would create an "F" force which will give the system with "m" mass an "a" acceleration. When you release the air in the ballon , you will see an accelarated (not stable) motion. That will prove the theroem "F=ma" which is the basic of Newton's second law.

Hi. Tape the balloon to the straw, feed the string through it and hang both ends, blow up the balloon and when you release it the answer will be revealed.
