A statement with an "I am" phrase could be used to communicate one's feelings in a non-confrontational manner. I hope this answer helps. Have a great day ahead.
The overall kinetic energy of the 60mph car is greater than the overall kinetic energy of the 30mph car. Because of this, it takes a greater force to stop the faster car because it has greater amount of kinetic energy (aka the amount of force needed to overcome the momentum of the faster car is larger).
Natural systems are systems that came into being by natural processes. Like the rain cycle.
Technological systems are those to whom people intervened or designed. Like diverting water for a rider for land irrigation.
