1. The use of a flimsy retort stand meant that when the pendulum was in the motion the retort stand was also swaying slightly. Explain this.



2. p=mv, torque=rmg



3. I am a bit stumped on this one. My teacher suggested I look into the torque of the pendulum - the friction at the point where the pendulum joined the retort stand and the distance that the pendulum was held from the stand. I originally thought that conservation of momentum was the way to go. I know that the initial momentum of the object was zero but I don't really know where to go next with that.
