Why do passengers hold on to support to prevent themselves from swaying in a turning bus?

Passengers hold on to support in a turning bus to maintain their balance and stability. When the bus turns, the centrifugal force pushes them outward, which can cause them to sway or feel unsteady. By gripping handrails or other supports, they can counteract this force and prevent falling or losing their equilibrium. This action helps them feel more secure and comfortable during the ride.
