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.
