Acceleration and Deceleration


  • Acceleration
  • Deceleration

Acceleration is another word for 'accelerate'. When a car accelerates, it will therefore be moved from a low speed to a higher speed. In cars, an acceleration time of 0 to 100 km is often specified in a few seconds.

A number of factors influence the acceleration of the car, namely: the engine power, the vehicle mass, the speed of gear changes, the gear ratio of the gearbox, the rolling resistance of the wheels on the road surface and the air resistance, all of which increase with higher speed.

Deceleration is another word for 'slow down'. Usually, deceleration is initiated by braking (also called braking deceleration). It is also possible to decelerate by releasing the accelerator pedal, so that the vehicle will slowly come to a stop due to its own mass inertia.
