Reaction Rocket: projectile launch via momentum transfer in slow motion. The superball/straw base bounces off the table top and then immediately collides with the bottom of the rocket sending it off with a velocity slightly less than 3 times the velocity of the rising ball (true if the ball is more than three times the mass of the rocket). Newton's third law in action! Note that the rocket rises much higher than the drop height (up to 9 times higher). Follow the link in my profile for info on where to get this and many other physics toys. #elastic #elasticcollision #collision #physics #physicstoy #newtons3rdlaw #inelastic #restitution #coefficientofrestitution #superball #momentum #conservationofmomentum #science #scienceisawesome #projectile #astroblaster A video posted by physicsfun (@physicsfun) on May 1, 2016 at 10:25am PDT
