In which scenario would a vehicle experience roll?

A vehicle experiences roll primarily during sharp turns due to the dynamics of centrifugal force and the vehicle's center of gravity. When a vehicle turns sharply, the inertia causes the body to lean to the outside of the turn. This shifting of mass can result in the vehicle's wheels losing grip on the road, especially if the turn is taken too quickly for the vehicle's design or if the road conditions are poor.

The center of gravity, which is the point where the vehicle's mass is evenly distributed, plays a crucial role here; if it is too high or if the vehicle's suspension is not appropriate, the likelihood of a rollover increases significantly during tight maneuvers. Thus, the scenario of making a sharp turn directly correlates to the potential for a vehicle to roll over.

In contrast, during acceleration or braking, the vehicle's weight shifts forward or backward, respectively, but this does not typically cause the rolling effect as seen in lateral movements during a turn. While a vehicle can lose control in these scenarios, the specific action that leads to roll is the lateral forces experienced in a sharp turn. Being stationary does not induce any dynamic forces capable of causing roll.
