Rockets range in size from fireworks so small that ordinary people use them, to the immense Saturn V that once propelled massive payloads toward the Moon. The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses are explained by the same physical principle: “Newton’s third law of motion states that matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains.” According to lumenlearning.com. A rocket’s acceleration depends on three major factors, consistent with the equation for acceleration of a rocket.The nose cone is an essential to cut through the air so the rocket can go further. The fins are to help stabilize the rocket while inflight. According to NASA, “for the coasting case, both lift and drag produce clockwise torques about the center of gravity;”
A scientific research website stated, “Rocket physics plays a crucial role in the modern world. From launching satellites into orbit to testing Intercontinental Ballistic Missiles (ICBMs)”,” Principles of rocket mechanics have innumerable applications. The history of rockets goes back to the first century Chinese who used rockets as fireworks to ward off bad spirits, and since then rockets have evolved tremendously.”
This is explained through Sir Isaac Newton’s 1st law of motion, stating, “An object in motion stays in motion, an object at rest stays at rest unless acted on by another force.”
The tail of the rocket will swing to the left under the action of both forces and the nose will move to the right.” In both cases, the lift and the drag forces move the nose back towards the flight direction. Engineers call this a restoring force because the forces “restore” the vehicle to its initial condition, and the rocket is determined to be stable. Also, NASA has stated, ”the conditions for a stable rocket are that the center of pressure must be located below the center of gravity. NASA said the stability can be increased by lowering the center of pressure, increasing the fin area, or by raising the center of gravity, adding weight to the nose.
As to why would this be important is for running aerodynamic traces: that decision is up to you.
