Final answer:
The example of inertia is a person in a car turning right while their body leans to the left, due to the tendency of the body to maintain its straight-line motion in accordance with Newton's first law of motion.
Step-by-step explanation:
The scenario that exemplifies inertia is 'A person rides in a car that is turning right and his body leans to the left.' This is due to inertia, which is a property of matter that causes it to resist changes in its state of motion. According to Newton's first law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The scenario mentioned involves the car changing direction due to the turn, but the passenger's body attempts to maintain its straight-line motion, which is why it leans in the opposite direction of the turn.
Another way to look at it is from the noninertial frame of reference; inside the car, it feels as if a force is pushing you toward the left when in reality it is the car that is moving to the right, and your body attempts to stay on its original path due to inertia.
