Circus | Circus Physics: Linear Momentum | PBS

Duration: 01:58
Program: Circus

Platform trapeze requires athleticism, good timing, and a strong understanding of the principle of conservation of linear momentum. The momentum of a system is the sum of the momenta of all the objects in it. Like energy, the momentum of a closed system is always conserved. In this video you'll learn how platform trapeze artists use this fact to soar beneath the big top.
