Question: What are the advantages of friction?
- Increases vehicle safety
- Helps in writing with a pen
- Enables walking without slipping
- Enhances heat generation
Answer: A) Increases vehicle safety
Advantages of Friction Solution:
Friction offers several advantages in various aspects of our daily lives. Firstly, it plays a crucial role in increasing vehicle safety (Option A). When driving, the friction between your tires and the road surface provides the necessary grip, allowing you to maintain control of your vehicle, especially during braking and turning. This prevents accidents and ensures a safer driving experience.
- Additionally, friction is essential in enabling us to write with a pen (Option B). The friction between the pen’s tip and the paper surface creates resistance, allowing the ink to be transferred onto the paper as we write. Without friction, writing would be virtually impossible.
- Moreover, friction enables us to walk without slipping (Option C). The friction between the soles of our shoes or feet and the ground prevents us from sliding and falling, ensuring stability as we move about in our daily activities.
- Lastly, friction also has advantages in terms of heat generation (Option D). In various machinery and devices, friction between moving parts can generate heat, which can be harnessed for various purposes such as powering engines or heating elements.
Here are some other advantages of friction:
- It helps us to stop moving objects. When we apply the brakes on a car, friction between the brake pads and the wheels slows down the car.
- It helps us to write on paper. The friction between the pen or pencil and the paper creates a force that allows us to move the writing instrument across the surface.
- It helps us to climb stairs. The friction between our shoes and the stairs prevents us from slipping.
- It helps to keep us warm. When we rub our hands together, friction generates heat, which helps to warm us up.
Overall, friction is a complex force that has both advantages and disadvantages. It is important to understand the different aspects of friction to use it to our advantage and minimize its disadvantages.
Distinguish between Western Ghats and Eastern Ghats
The Western Ghats and Eastern Ghats are two significant mountain ranges in India, differing in location, elevation, and biodiversity. The Western Ghats run parallel to the western coast, stretching from Gujarat to Tamil Nadu, with a higher average elevation and a rich variety of flora and fauna. In contrast, the Eastern Ghats are more scattered, located along the eastern coast, from Odisha to Tamil Nadu, with lower altitudes and less biodiversity. The Western Ghats are recognized as a UNESCO World Heritage site, while the Eastern Ghats play a crucial role in supporting agriculture and water resources for the region.
