Question

In which of the following sports does reduced friction help to improve performance?

• A. Foot Ball
• B. Basket Ball
• C. Skiing
• D. Tennis

Answer 1

The Correct Option is C

Reduced friction is beneficial in certain sports as it allows for smoother movement and improved speed. In the context of the given options, the sport in which reduced friction plays a crucial role in enhancing performance is Skiing. 

Explanation:

• Skiing: In skiing, reduced friction between the skis and the snow is essential for a skier to glide smoothly and quickly down slopes. This reduction in friction is primarily achieved through the design of the skis and the wax applied to them, allowing for efficient movement and control.
• Football, Basketball, Tennis: These sports rely more on traction and grip to change directions quickly and for better control of movements. Increased friction is generally more advantageous in these sports to prevent slipping and maintain stability.

Thus, reduced friction is most advantageous in Skiing.

Answer 2

Reduced friction plays a crucial role in skiing by allowing smoother gliding and faster movement on snow. Skiers rely on the reduced friction between their skis and the snow surface to minimize resistance, enabling them to move more efficiently and with greater control.

When friction is reduced, the skis can slide more easily, which results in a smoother ride down the slope. The lower the friction, the less effort is required to maintain speed, and the skier can travel faster with less energy expenditure. To achieve this, ski surfaces are often treated with wax, which further decreases friction and enhances glide, ensuring that skiers can move with greater ease and precision.

Additionally, reducing friction improves stability, allowing skiers to make sharp turns and navigate varying terrains with greater confidence. With less resistance, athletes can focus more on technique and speed, contributing to better performance in competitive events.

In conclusion, reduced friction is essential for skiing, as it allows for smoother and faster movement, enhancing the overall performance and enjoyment of the sport, while making it safer and more efficient for skiers.
