Horizontal force: Air resistance (drag) and possibly wind; in ideal vacuum, only thrust angle matters, but on Earth, aerodynamics cause curvature.
Example answers: Saturn V rocket (action-reaction thrust), Space Shuttle solid rocket boosters (similar fuel design), Apollo guidance systems (trajectory physics). october sky science worksheet answers
Step: Revising the hypothesis / redesigning the experiment based on results. Horizontal force: Air resistance (drag) and possibly wind;
Below is a complete, ready-to-use worksheet and answer key. Name: ________________________ Date: ________________________ in ideal vacuum
Fins: Provide aerodynamic stability, keeping the rocket flying straight by moving the center of pressure behind the center of mass.
