Final answer:
When a vehicle's front wheel slips off the edge of the road while in motion, it experiences a fictitious force called the centrifugal force that pushes the vehicle and its occupants away from the center of the turn. The sharper the curve and the greater the speed, the more noticeable this force becomes.
Step-by-step explanation:
When the front wheel of a vehicle slips off the edge of the road while in motion, it experiences a force called the centrifugal force. This force is a fictitious force that appears to push the vehicle and its occupants away from the center of the turn. It is caused by the inertia of the occupants, who want to continue moving in a straight line, while the vehicle is turning off that straight-line path.
The centrifugal force becomes more noticeable when the curve is sharper and the speed of the vehicle is greater. It is important for drivers to be aware of this force and take appropriate measures to prevent accidents.
