Talk:A-level Physics/Forces, Fields and Energy/Further dynamics

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) State each of Newton’s laws of motion. &#10004;
 * 2) Define, recall and use (linear) momentum as the product of mass and velocity. &#10004;
 * 3) Define force as rate of change of momentum, and use this definition in situations where mass is constant.
 * 4) State the principle of conservation of momentum. &#10004;
 * 5) Use the principle of conservation of momentum in simple applications including elastic and inelastic interactions between two bodies in one dimension, and the separation of an initially stationery object into two parts. (Knowledge of the concept of restitution is not required.)

Elastic and inelastic collisions
It would be helpful to include brief comments about elastic and inelastic collisions here, particularly with reference to the non-conservaton of kinetic energy in inelastic collisions which confuses some of my pupils.
