15 Which of the following are types of friction? A Inertia B Static C Fluid D Gravity E Sliding

Friction is a fascinating force that comes into play in our daily lives! Static friction keeps objects at rest, preventing them from sliding unless a sufficient force is applied. Sliding friction, on the other hand, occurs when two surfaces slide against each other – think of it as the resistance you feel when you push a book across a table. The world of friction isn't just theoretical; it has real-world applications! For instance, engineers design tires with specific tread patterns to maximize grip through friction, ensuring safety on the road. In sports, athletes often rely on the balance of static and sliding friction to enhance their performance, like in a sprinter's start or a skateboarder's slide.
