Rocket engines burn chemicals such as petroleum and liquid oxygen at very high pressures and temperatures to turn the chemical energy into motion. In some cases (such as NASA rockets), the force created can be over 1,000,000 pounds-force (4,400,000 newtons). A garden hose shows how moving fluid can create a force.
In general, the INFJ is a deeply warm and caring person who is highly invested in the health of their close relationships, and puts forth a lot of effort to make them positive. They are valued by those close to them for these special qualities.

ISFJs are true altruists, meeting kindness with kindness-in-excess and engaging the work and people they believe in with enthusiasm and generosity.
