High friction is needed to prevent slipping and provide traction between surfaces in various applications, such as car tires on the road or shoes on the ground. It helps to ensure stability, control, and safety by resisting the relative motion between objects in contact. Additionally, high friction is essential for efficient energy transfer and braking.
When climbing, high friction is needed when the holds are small or difficult to grip. By generating more friction between your hands or feet and the surface of the holds, you can improve your grip strength and stability, making it easier to climb. Additionally, high friction can help prevent slipping and falling while climbing.
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
The force needed to move a pencil across a desk would depend on the friction between the pencil and the desk surface. If there is low friction, only a small force would be needed. If there is high friction, a greater force would be required to overcome it.
High friction is needed in scenarios where there is a need for better grip and traction, such as in car tires on a wet road, rock climbing shoes on a steep surface, or brake pads on a bike. Increasing friction helps to prevent slipping and sliding, ensuring safety and control in various activities.

Rotating bearings.
The coefficient of friction between the person and the rug is high and a lot of force is needed to overcome that.
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
Example of high friction is a really rough surface like sandpaper.
