It's inertia. The car accelerates one way, but you keep going per Newton's first law. Consequently, you (with your reference frame pegged to the car) feel as if you are accelerated the opposite way. We call this a pseudoforce effect, because you feel a force on you that isn't real to an outside inerital observer.

First let me give newton's Laws of motion.
# An object will remain at rest, or continue to move at a constant velocity, unless a resultant force acts on it.
# Net force on an object is equal to its mass multiplied by its acceleration.
# For every force acting on an object, the object will exert an equal, yet opposite, force on its cause
he laws in detail
Newton's laws of motion describe the acceleration of massive partcles. In modern language, the laws may be stated as:
First Law
If no net force acts on a particle, then it is possible to select a set of reference frames, called inertial reference frames, observed from which the particle moves without any change in velocity. This law is often simplified into the sentence "An object will stay at rest or continue at a constant velocity unless acted upon by an external unbalanced force".
Second Law
Observed from an inertial reference frame, the net force on a particle is proportional to the time rate of change of its linear momentum: F = d[mv] / dt. Momentum is the product of mass and velocity. This law is often stated as F = ma (the force on an object is equal to its mass multiplied by its acceleration). Also a = F / m, if you are trying to find the acceleration of an object.
Third Law
Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence "Every action has an equal and opposite reaction".
--> In the given interpretation mass, acceleration and most importantly force are assumed to be externally defined quantities. This is the most common, but not the only interpretation: one can consider the laws to be a definition of these quantities. Notice that the second law only holds when the observation is made from an inertial reference frame, and since an inertial reference frame is defined by the first law, asking a proof of the first law from the second law is a logical fallacy.
Explanation for what u asked.
The car moves in specific direction.
You are in inertia. when the car takes a turn the direction of velocity changes there by introducing a acceleration.
A force v*v/r comes into picture and makes all this effect.
since you are still in inertia of old direction of velocity you will get the effect.

Newton's first law. An object in motion tends to stay in motion in a staight line unless acted on by an outside unbalanced force. When the car turns the passengers continue moving forward in a straight line until they come in contact with the side of the car which pushes them along the same path as the car.

Passengers get thrown in a car in a fast speed is a result of velocity and acceleration. velocity is the speed in a direction while acceleration it is both speed and acceleration. Motion change the position of the body that's why it move.

this is becouse of momentum
the passengers get thrown to the side becouse the pressure exerted by the is felt by the pssengers
