Capping downside but leaving upside gives momentum, due to something like the third law of motion.
- Capping downside but leaving upside gives momentum, due to something like the third law of motion.
- Third law of motion: for every action there is an equal and opposite reaction.
- Put a solid surface and then explode something on the other side, it pushes the surface away.
- A rocket!
- A physical asymmetry that creates momentum.
- Similarly, when you cap downside and leave uncapped upside, you give a way for the system to propel itself.
- The only way for the energy to go out is to push you along towards the upside.
- A conceptual asymmetry that creates momentum.
