The initial momentum of the rocket and fuel is. Pinit = (m + |dm|)(v) Pinit = m v + |dm| v. After the amount of fuel |dm| is burned the rocket increases its velocity to v + dv and its mass decreases to m so the final momentum of the rocket and fuel is. Pfinal = (m)(v + dv) + (|dm|)(v – ve)

“Rocket science” is very similar to mechanical engineering and requires a similar education and skill set. Most people consider it to be hard because it is very mathematically intensive. In university, you would need to take differential calculus and finite element analysis.

Most supersonic aircraft, rockets, and missiles use a nose shape very similar to a cone but a little more rounded to provide more internal volume. This shape is called an ogive (pronounced “oh-zheeve” or “oh-zhive”). The faster the vehicle is designed to go, the more pointed the ideal aerodynamic nose shape becomes.

A: A parabolic nose cone reaches a higher altitude than a conical nose cone because it creates less drag. Drag is the force of flight that acts in the opposite direction of motion. Air flows around a parabolic nose cone better than it flows around a conical nose cone.

Maximum performance of each extends into hundreds of feet in terms of distance or altitude. Similarly, the velocity of these projectiles may exceed 100 mph. A simple rocket powered by pneumatic or air pressure may be used to demonstrate thrust and Newton’s Laws.

The primary stage of a rocket is the first rocket engine to engage, providing the initial thrust to send the rocket skyward. Usually the first stage is larger than the next stage, or stages, because it must transport not only its own weight, but the weight of the rest of the rocket.

If the speed of a rocket is less than the speed of sound (1,200 km/h in air at sea level), the best shape of a nose cone is a rounded curve. At supersonic speeds (faster than the speed of sound), the best shape is a narrower and sharper point.
