Newton’s Third Law
- Synopsis
- Examines two important consequences of Newton’s Third Law stating that action and reaction are equal and opposite. First, for a closed system, the centre of mass of the system moves uniformly or stays at rest. Second, in collision processes momentum is conserved for elastic collisions. The first consequence is theoretically developed and illustrated by showing gliders on an airtrack connected by a spring. A marker was placed in the centre of the mass of the two pucks and, using after images, it was shown this point moved uniformly. The principle was extended to colliding pucks. The second half of the programme examines colliding pucks on an air table demonstrating linear momentum conservation for elastic collisions. The results are extended to include the weaker principle of kinetic energy conservation.

- NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
