In addition to air drag, you have to consider gravity as well.
The air drag force acts in the opposite direction of the rocket's motion, slowing it down and reducing its acceleration. This decreases the overall efficiency of the rocket and affects the ideal rocket equation by decreasing the amount of thrust that can be produced.
Yes, air drag is a significant factor in rocket design. It must be carefully considered and minimized in order to achieve optimal performance and efficiency in flight. This is especially important for rockets that are designed to travel at high speeds and altitudes.
In the ideal rocket equation, air drag is accounted for by including a drag coefficient in the equation. This coefficient takes into account the shape and size of the rocket, as well as the properties of the surrounding air, and is used to calculate the amount of drag force acting on the rocket.
No, air drag cannot be completely eliminated in rocket flight. However, it can be minimized through careful design and engineering. This is often achieved by streamlining the shape of the rocket and using materials that reduce drag, such as lightweight and aerodynamic materials.
Air density plays a significant role in air drag during rocket flight. The denser the air, the greater the drag force acting on the rocket. As a rocket gains altitude and enters thinner air, the amount of drag decreases, allowing it to achieve higher speeds and more efficient flight.
