Why rocket altitude does not increase proportionally?

In summary, the altitude of a rocket does not increase proportionally with time due to the forces acting on it. The weight of the rocket affects its altitude, as a heavier rocket requires more fuel and a lighter rocket can reach higher altitudes more easily. The rocket's engine plays a crucial role in providing thrust for lift-off and continued ascent. Air pressure also affects rocket altitude, with lower air pressure at higher altitudes making it more difficult for the rocket's engines to operate efficiently. Finally, the shape of the rocket can impact its aerodynamics, air resistance, stability, and control during flight, all of which can affect its altitude capabilities.

Hello Starnair, :welcome: !

Nice of you to think of PF, but the idea here is that we help you, not that we do your assignments for you (after all, we don't get the credit afterwards -- you do !).

So you suspect there is a relation between band stretch and altitude. (I agree). Did you measure them ? Make a plot of stretch (horizontal) and altitude (vertical) ?

What have you learned so far that might be of help ? Know the kinetics relationships ?
 

1. Why doesn't the rocket altitude increase proportionally with the amount of fuel?

The rocket altitude does not increase proportionally with the amount of fuel because there are other factors that affect the flight of a rocket, such as air resistance and gravity. As the rocket travels higher, the air becomes thinner and the force of gravity becomes stronger, making it more difficult for the rocket to continue climbing.

2. What is the maximum altitude a rocket can reach?

The maximum altitude a rocket can reach depends on its design, the amount and type of fuel, and the amount of payload it is carrying. On average, rockets can reach altitudes of around 100 miles, but some specialized rockets have been able to reach altitudes of over 300 miles.

3. How does the shape of a rocket affect its altitude?

The shape of a rocket can affect its altitude in several ways. A streamlined shape can reduce air resistance and allow the rocket to travel faster and higher. Additionally, the shape of the rocket's nose cone can help to reduce drag and improve its aerodynamics, allowing it to reach higher altitudes.

4. Why does the rocket's altitude fluctuate during flight?

The rocket's altitude can fluctuate during flight due to changes in air resistance, wind patterns, and the forces of gravity acting on the rocket. For example, if the wind suddenly changes direction, it can push the rocket off course and affect its altitude. Additionally, as the rocket burns fuel and becomes lighter, the force of gravity will have a greater impact on its flight path.

5. Can a rocket continue to increase in altitude indefinitely?

No, a rocket cannot continue to increase in altitude indefinitely. As the rocket travels higher, the air becomes thinner and the force of gravity becomes stronger, making it more difficult for the rocket to continue climbing. Eventually, the rocket will reach a point where it can no longer overcome these forces and will level off or begin to descend.
