/* Some explanations to the attachments:
|
|
Parachute: This will increase the air friction, reducing the maximum speed.
|
|
It will not have too much of an effect on slow speeds, since air
|
|
friction only becomes important at higher speeds.
|
|
Anvil: It increases the weight of the kart.But this will NOT have any
|
|
effect on karts already driving at highest speed: the accelerating
|
|
force is independent of the mass, so it is 0 at highest speed
|
|
(engine force = air- plus system-force) and only this value gets
|
|
divided by the mass later --> at highest speed there would be no
|
|
effect when the mass is changed, only at lower speeds the acting
|
|
acceleration will be lower.Reducing the power slows the kart down,
|
|
but doesn't give the feeling of a sudden weight increase.
|
|
Therefore the anvil will reduce by a certain factor (see physics
|
|
parameters) once when it is attached. Together with the mass
|
|
increase (lower acceleration) it's sufficient negative.
