← ScienceWhich effect happens when a drag racer's mass increases?
A)Increased normal reaction force✓
B)Reduced combustion chamber pressure
C)Enhanced exhaust gas velocity
D)Decreased aerodynamic lift
💡 Explanation
Increased relativistic mass causes greater downward gravitational force affecting the normal force, because of Einstein's mass-energy equivalence; therefore, a normal reaction force increase occurs, rather than combustion changes, with negligible lift variation at low speeds.
