Soon, my physics students will be covering projectile motion. I've been
thinking of doing a new lab, but wanted to see if someone else had
already done it, and/or suggestions.
I'm thinking of having the students roll marbles down an incline, have it
roll across the lab table a short distance, and mark where it lands on
the ground (get an average of its landing distance).
From the information as to where it lands and the height of the labtable, the students would then calculate its initial horizontal velocity.
Then comes the challenging part. I'm thinking of giving the students 2-4
rings (about 2-3 inches in diameter) and they would have to place them
in equal intervals of the marble's path, so that the marble passes
through each ring.
Has anyone done a similar lab? Any suggestions? If someone has already
done this, could someone email me their lab?
Thank you in advance,
Dwight
