What causes a car to not accelerate properly?

If your car is not accelerating properly, check the air filter. The air filter traps dirt, debris and other impurities to keep them from entering the combustion chamber. A clogged air filter starves an engine of much-needed air, skewing the air/fuel mixture that affects acceleration.

Why does a naturally aspirated car not accelerate?

Oxygen is a crucial part of the mixture in the combustion chamber and there is less oxygen at higher elevations. Naturally aspirated cars are more likely to have this problem than forced-induction (turbocharged or supercharged) vehicles as the forcing of air into the engine can somewhat compensate for having less oxygen in the environment.
