← ScienceWhich risk increases when a rocket's acceleration nears Earth's gravitational acceleration?
A)Fuel exhaustion before target velocity✓
B)Navigation system lock-in malfunction
C)Structural failure induced at resonant frequency
D)Internal components experience increased inertial lag
💡 Explanation
Fuel consumption increases non-linearly due to the equivalence principle; gravitational force equals inertial force. Achieving target velocity becomes improbable because of increased propellant volume requirements that surpass calculations, therefore exhaustion is significantly elevated here, rather than only drag or inertial lag.
