For Questions That Don't Merit Their Own Thread in Science & Spaceflight Posted April 6, 2022 Does the flight trajectory of an object is affected by the rate of acceleration and how the atmospheric drag behaves during the flight? For example, there are 2 projectiles launched into space at suborbital trajectory. Both has the same delta-V, same mass and same angle of launch. However, projectile A is launched normally using rocket engines while projectile B is shot using mass driver. In this case: 1. Projectile A has a gradual acceleration to max speed and atmospheric drag that steadily rises as it flies through atmosphere before it finally reached space 2. Projectile B has instantaneous acceleration to max speed and the atmospheric drag is instantaneously jumped to max before it finally reached space Assuming these 2 have the same delta-V (but different flight characteristic), does the trajectory produced are identical to each other?
