In general, binding energy represents the mechanical work which must be done in acting against the forces which hold an object together, while disassembling the object into component parts separated by sufficient distance that further separation requires negligible additional work.

  This is a general definition of binding energy. For those of you who do chemistry, can you relate the concept of binding energy to what you know of endothermic and exothermic reactions?

essentially far enough so that the strong nuclear force can no longer cause the particles to interact).
- Gwyneth Cooper on 08 Sep 08
  
  Remember, the strong nuclear force only acts over very short distances. An atom is about 1x10-10 m across, so the force must work on a shorter range than this.

Because a bound system is at a lower energy level than its unbound constituents, its mass must be less than the total mass of its unbound constituents

  Find the rest mass of an atom of tritium and compare with the rest mass of the unbound nucleons. Use this information to find the energy difference between the unbound nucleons and the atom

The answer is that this mass does not "disappear" into energy (a common misconception); rather, transformed to heat or light, this mass may move away to another location
- Gwyneth Cooper on 08 Sep 08
  
  This is true, but is above the level required at Y13 physics. You need to know that the mass is not lost from the system, but can use the explanation that it is used to find the energy for the binding. Don't worry about the rest of this explanation.

THis site looks like it could be really useful for another explanation of some physics concepts, for when your textbook needs some support

notes shm y13

shared by Nigel Crawford on 04 Sep 08 - Cached

The oscillator's motion is periodic; that is, it is repetitive at a constant frequency. The restoring force within the oscillating system is proportional to the negative of the oscillator's displacement and acts to restore it to equilibrium. The velocity of the oscillator is maximum as it passes through equilibrium, and zero as it passes through the extreme positions in its oscillation. The acceleration experienced by the oscillator is proportional to the negative of its displacement from the midpoint of its motion.

  How would you use this information to answer the question: "describe SHM, including an example, using the terms period, amplitude, frequency, restoring force?"

  Note how the displacement and acceleration are completely out of phase, while the displacement and velocity are 90 degrees out of phase. With reference to a mass on a spring undergoing SHM, explain why this is the case
