Footage description: Pip Youngman demonstrates the home experiment kit chart recorder. Richard Fendrich introduces the programme with a very simple example of a free body diagram showing two bodies on a horizontal plane and connected by a cord. He then works out equations for the motion of such a system. An animated diagram shows a more complex system, one with a drum, lifts and counterlifts. Fendrich works out the equations for motion for the model when there is friction and when there is no friction. A practical example of this type of motion is examined using a diagram of a mine shaft lift. Fendrich works out the equations which are shown on a board together with the free body diagram of the system. Fendrich next examines the free body diagram of a block and tackle system. He works out the equations for the system's motions on a board. Fendrich uses a block and tackle system to demonstrate the theoretical calculations above It also allows him to find the final equation for the system.
