of one of the solid rocket boosters” (Feynman27). It was a mixture of structural failures that caused the shuttle to break apart. The cause of the explosion was the failure of O rings in the right (SRB) solid rocket booster due to the cold weather. This caused the O rings to allow hot gases to leak out of the booster through the joint. These rubber rings sealed the joint between the two lower segments of the booster. The combustion gas leak passed through the right Solid Rocket Motor aft joint and

CONSERVATION OF MOMENTUM PRACTICAL WRITE UP AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was
