What is wanted friction?
This presumably refers to friction which we find useful. For instance, if you stand on a ladder which is leaning against a wall, it is friction which stops the ladder from slipping. When you walk, friction between your shoes and the ground enables you to push yourself forwards. If the friction is not big enough, you just slip, as on ice.
How does friction keep our feet from slipping?
Friction plays a crucial role in preventing slipping, and it operates at the interface between surfaces in contact. In the case of walking or standing, the interaction between the soles of our shoes or feet and the ground relies on friction to provide stability. Here's how friction helps keep our feet from slipping: Surface Interaction: Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. When we stand or walk, the soles of our shoes or feet are in contact with the ground or floor. The frictional force at this interface resists any attempt to slide or slip. Microscopic Surface Irregularities: Even seemingly smooth surfaces have microscopic irregularities. Friction occurs due to the interaction of these irregularities at the molecular level. When pressure is applied, the irregularities lock together, creating a resistance to sliding. Normal Force: Frictional force is directly proportional to the normal force, which is the force exerted perpendicular to the surfaces in contact. In the case of standing, the normal force is the weight of the person pressing down on the surface. For walking, the normal force varies as the foot makes contact and pushes off. Coefficient of Friction: The coefficient of friction is a measure of the frictional force between two materials. It depends on the nature of the materials in contact. A higher coefficient of friction means a stronger frictional force and better resistance to slipping. Traction: Traction is a term used to describe the grip or adhesion between the shoe or foot and the ground. The greater the friction, the better the traction. This is particularly important for activities like walking, running, or participating in sports where maintaining grip is essential. Shoe Design: The design of shoe soles also plays a role in enhancing friction. Tread patterns, the choice of materials, and the presence of features like grooves or studs can all affect the interaction between the shoe and the ground. While friction is essential for preventing slipping, it's worth noting that certain factors can influence it. For example, walking on slippery surfaces, wearing shoes with worn-out soles, or walking on surfaces with low friction coefficients (such as ice) can reduce the effectiveness of friction, making slipping more likely. Additionally, substances like water, oil, or ice can significantly impact the coefficient of friction and increase the risk of slipping.
Walking would be impossible without friction?
Yes, your foot needs contact with the ground to walk, because it pushes itself off of the ground. With no friction, your foot could not stay on the ground to push off. It's similar to walking on ice except... impossible.
What causes a ball to stop rolling?
the friction and the motion of the ball both combined
What type of friction is there?
1) Static Friction: When it's hard to move an object (i.e.: moving a large refrigerator box is difficult because of the large mass pressing down and the static friction between the box and the floor)2) Sliding Friction: Tiny friction particles in between objects that slow them down (i.e.: moving a cafeteria tray in the lunchline--there's a little bit of friction between the tray and the metal bar, which causes the tray to move slowly)3) Rolling Friction: The friction between wheels (or anything rolling) and the ground. (i.e.: riding a bike. Without rolling friction, we would speed out of control. Walking would also be impossible because our feet collide with the pavement and gently roll off. With no friction, we'd be slipping and sliding everywhere! =D)
Does friction affect your life?
Yes, because with out friction everything and/or every one would be slipping on the ground.

Why is it difficult for persons wearing pencil heels to walk on a softer ground?
the ground is slippery and there is no friction
Does snow increase friction between your shoes and the ground?
Snow decreases the friction between your shoes and ground. That's why cars slide in the winter.

What are some facts about friction?
Friction is a force, of resistance, that takes place when two or more objects make contact and when there is movement with one another. Friction keeps your feet on the ground and prevents you from slipping. Fricition is just like gravity.

How can you increase the amount of friction between your shoes and the ground?
by increasing the roughness of the ground or increasing the sole of the shoes
What are two ways that friction is helpful and harmful when riding a bike?
Friction can be both harmful and helpful. Without friction the tires of the bike could not push against the ground to move forward, and the brakes would not stop the bike. However, friction can cause parts of the bike and the tires to wear down. Also, to overcome the friction between the tires and the road you need to pedal harder to go faster.friction is helpful to stop the bike when you put on the brakes but it may be harmful by slowing your speed down. and if you hit the brakes hard at a sudden moment, you could tumble or flip
Do snow increase the friction between your shoes and the ground?
Yes
What would happen if there was no friction between a rolling ball and the ground?
no
