So almost any car will be faster at the start for the liner, and you didn’t fly on the hike, because as soon as this fool took off and climb, it presses into the seat normally, brighter than on the car. After all, the speed gain after 250-350 km / h for the liner is much higher than that of the car, even from zero to 100

Perhaps, such sensations are also connected with the fact that the cabin of the plane is sealed, unlike the cabin of the car.

In the same way, riding a motorcycle is perceived in a completely different way in relation to riding a car: the roar of the engine , pressure and noise of incoming air currents create the "feeling of speed" so dearly loved by motorcyclists.

Feelings can be deceiving. The numbers are more objective and let's turn to them.

  • Vehicle BMW X5 M and X6 M accelerate from 0 to 100 km / h in 4.2 seconds, which corresponds to an acceleration of 6.61 m / s² or 0.67g .
  • Lada Kalina car: acceleration to 100 km / h in 13 seconds gives an acceleration of 2.1 m / s² or 0.22g.

  • Airbus A320 . The thrust of the engines F = 2 × 110 kN at the maximum take-off weight m = 75 T provides acceleration a = F / m = 2.9 m / s² or 0.3g. The Boeing 777 has the same takeoff acceleration.

  • F-14D Tomcat fighter . Catapult takeoff provides an acceleration of 24.8 m / sec² or 2.5g .
    It can be seen that the acceleration of BMW is higher than the takeoff acceleration of passenger aircraft, and the questioner does not drive Lada Kalina. The figures shown are taken from Wikipedia.
