Terminal velocity

The terminal velocity (also: speed limit ) is a term of the dynamics and kinematics, and refers to the speed at which an object has reached the end of its acceleration. An object reaches its terminal velocity when the braking forces have become so strong by increase or decrease the speed that forms an equilibrium of forces all the forces involved. The acceleration in reaching the final velocity is therefore zero.

Terminal velocity in free fall

In a free fall through the air, the terminal velocity is reached when the gravitational force is equal to the opposing force due to the air friction.

For the final speed ( maximum speed ) applies:

With:

The balance is reached, the final velocity is equal to the impact velocity:

Other uses

The term is also used in the art. In the automotive sector, for example, one speaks of top speed when the vehicle is limited by engine power and external circumstances can not continue to accelerate.
