Final answer:
Inertia makes your body resist the car's change of direction when turning right, causing a sensation of being pushed to the left, which is understood as a fictitious or inertial force.
Step-by-step explanation:
When you're in a car turning right, inertia causes your body to want to keep moving straight ahead, which you perceive as being pushed to the left inside the car. This sensation is due to a fictitious force known as the centrifugal force, which arises when the car is used as a frame of reference. From the Earth's perspective, following Newton's first law, there is no real force acting on you toward the left; rather your body continues in a straight line while the car turns right. During this motion, since the car is an accelerated frame of reference, your body experiences this inertial effect because it tends to resist changes to its state of motion due to inertia.
