FAQs on Motion of a Car on a Banked Road Video Lecture - Class 11

1. What is the concept of motion on a banked road?
Ans. Motion on a banked road refers to the movement of a car or vehicle on a road that is inclined or angled to one side. The banked road is designed in such a way that it helps vehicles maintain stability and prevent skidding or slipping during turns.
2. How does the banking of a road affect the motion of a car?
Ans. The banking of a road affects the motion of a car by providing a centripetal force that helps the car turn smoothly without skidding. When a car approaches a banked road, the banked surface exerts a normal force on the tires, which creates a frictional force towards the center of the curve. This frictional force acts as the centripetal force and allows the car to make the turn safely.
3. What factors determine the ideal banking angle for a road?
Ans. The ideal banking angle for a road depends on various factors such as the speed of the vehicles using the road, the radius of the curve, and the coefficient of friction between the tires and the road surface. These factors need to be taken into account to ensure that the banking angle is sufficient to provide the necessary centripetal force for vehicles to safely navigate the curve.
4. Can a car safely travel on a flat road as well as a banked road?
Ans. Yes, a car can safely travel on both a flat road and a banked road. On a flat road, the car relies on friction between the tires and the road to maintain stability during turns. On the other hand, a banked road provides an additional centripetal force that aids in turning and prevents skidding. However, it is important for drivers to adjust their speed and maintain control while driving on any type of road.
5. What happens if a car is driven too fast or too slow on a banked road?
Ans. If a car is driven too fast on a banked road, the centripetal force provided by the banking may not be sufficient to keep the car on the curve. This can result in the car skidding or sliding off the road. Similarly, if a car is driven too slow on a banked road, the tires may not experience enough friction to generate the required centripetal force, causing the car to drift away from the curve. Therefore, it is crucial to maintain an appropriate speed while driving on a banked road to ensure safe and smooth turns.
