Q

why does inertia create the sensation that you are being pulled toward the outside of the curve when driving through a curve?

A

you are traveling in a straight line, and inertia wants to keep you going in a straight line

16
Q

what transfers weight from one point of the vehicle to another?

A

acceleration
deceleration/braking
steering input/cornering
surface traction

17
Q

pitch

A

vehicle weight shifts rear to front or front to rear

18
Q

pitch

real life example

A
slowing down
speeding up
brake
release brake
accelerate

steeping on brakes quickly and your head swings forward

fast acceleration in a sports car and your head leans back

19
Q

roll

A

vehicle weight shifts side to side

20
Q

roll

real life example

A

sudden jerky steering

grade of road- highest point of road in the middle

taking curve too fast

braking and steering combinations

21
Q

yaw

A

vehicle’s rear tires lose traction and weight shift to one side (rear tires slide)

fishtail

22
Q

yaw

real life example

A

sudden braking

sudden excessive acceleration or sleeking

traction loss to a rear tire

tilted road left or right
