this is my plan for my science research project. i plan to pick 3-5 different balls (all of the same shape - round, and mass). im going to drop the balls from the same height, and on the same surface (concrete), and then i will record how high the different balls bounce on the same surface. I need some help. How could i record the height of the balls as i do not hav super slow mo eyes :L lol Could it be possible to record it on a camera and which program could i do to make it super slow mo. Could i also take multi-capture camera and take quick pictures of the balls bounce and record the highest bounce. Also which balls should i choose that are the same mass and obviously round. Thank you
