The passenger wants to stay in a straight line, he/she experiences inertia.
If you're traveling in a car going in a straight line then your body is moving at the same speed and in the same direction as the car. If the car then turns to the right, your body still wants to keep moving forward in a straight line so it feels like you're being thrown to the left. Even the car itself wants to keep moving in a straight line as that is the force that was acting on it. It is only the grip of the tyres on the road that pull the car to the right. This is why if a car goes around a bend to quickly it will go up on two wheels or flip over.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
Zero!!
Kinetic energy wants to keep the car going in a straight line.
When your body is traveling in a straight line it wants to continue going in a straight line, but the coaster car is not traveling in a straight line and it pulls you down. See related link.

Straight line at a constant speed = no acceleration
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
Yes
If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.
Slowing down or decelerating
Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.
The acceleration of an object that travels in a constant straight line velocity is zero.
