When a car makes a sharp left turn, what causes the passengers to move toward the right side of the car?

is it inertia??

Yes. Their inertia makes the natural path of their motion be a straight line. To keep going straight while the car turns, their bodies must move to the right. Eventually friction or side wall forces make them stay in their seats.

Yes, the passengers moving toward the right side of the car when a car makes a sharp left turn is due to inertia. Inertia is the property of matter that resists changes in its motion. When the car turns left suddenly, the passengers' bodies tend to maintain their current state of motion, wanting to continue moving in a straight line.

To explain this phenomenon, Newton's first law of motion, also known as the law of inertia, can be referenced. This law states that an object at rest will stay at rest, and an object in motion will continue moving in a straight line at a constant velocity, unless acted upon by an external force.

In the case of a car making a sharp left turn, the car is an external force acting on the passengers. As the car turns, it applies a force to the passengers toward the left side of the car. However, due to their inertia, the passengers resist this change in motion and tend to keep moving in a straight line. As a result, they seem to be pushed toward the right side of the car relative to their initial position.
