inertia
 

One feels being pushed by a forward force (whatever called), due to inertia, when the car decelerates.

One feels being pulled by a backward force (whatever called), due to inertia, when the car accelerates.

One feels being pulled by an outward force (whatever called), due to, again, inertia, when the car turns (or accelerates in a different direction).

The rock moves in circle by a centripetal force (or being accelerated in a different direction) and feels being pulled by an outward force (whatever called) due to, again, inertia.

Inertia is "Lag", "Lag" is the secret of golf, Inertia is the secret of golf.

Not sure if it is a secret - rather part of the equation per 2-N-1
