Final answer:
The observed effects during a left or right turn, such as the driver feeling forced to one side in a car, or a motorcycle tilting and turning by handlebar manipulation, can be explained by inertia and the gyroscopic action of the wheels, as well as the concept of fictitious force in a rotating frame of reference.
Step-by-step explanation:
The question pertains to how attitude control differs when a vehicle makes left versus right turns, observed in the context of a physics principle known as inertia and Newton's first law. When the motorcycle rider pulls back lightly on the right handlebar, it causes the cycle to tip to the left. This tipping effect is due to the gyroscopic action of the motorcycle's wheels, which generates a reaction force that creates the leftward lean and facilitates the left turn. The same principle applies in a car, where turning right results in the driver feeling a force to the left because from the car's frame of reference, the driver wants to continue moving straight due to inertia while the car changes direction.
This can also be explained by the concept of fictitious force in a rotating frame of reference, such as when inside the car making a turn. In the Earth's frame of reference, the driver is moving in a straight line until acted upon by an external real force, which in this case, is the force exerted by the car seat that pushes the driver to follow the car's new direction of motion.
