Linear Air Resistance
Horizontal motion
If
is unity then the velocity is exponentially approaching zero.- : negative sign indicates a retarding force and is a proportionality constant
- ;
The displacement is given by
Example: falling object with linear air friction
Consider a ball falling under the influence of gravity and a frictional force that is proportion to its velocity
let
- coefficient of air resistance
- Terminal speed
The posiiton as a function of time may be determined by directly integrating the above equation
