MATH.7:3 - Forces
| Force | Tension |
|---|
| Familiar carrier and chosen structure | The same set can carry several operations with different identities and laws. |
| Reversible elements and preserved work | Recovering elements supplies the means to transport operations; it does not choose which operations matter. |
| One convenient representation and several quantities | A change can simplify one calculation while complicating another. |
| Reusable proof and computing cost | Transport can reuse an algebraic argument, while repeated encoding and decoding can make a calculation expensive. |
