Circus Physics: Projectile Motion

  • Aired: 06/01/2010
  • 02:24
  • Rating: NR
Jugglers know that if you throw an object into the air, it will follow a curved path -- as the ball moves horizontally, gravity pulls it down vertically. Physicists call this projectile motion. In this video you will learn why projectile motion is important to jugglers and why it is so hard to juggle multiple objects.
