What else can I help you with?
Does a rough surface have a lot of friction?
Yes, rough surfaces generally have more friction than smooth surfaces because there are more points of contact between the two surfaces, leading to greater resistance when attempting to slide or move one surface over the other.
Does rough surfaces exert greater friction?
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.
Does surface type affect the force of friction?
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
Is greater force needed to move an object over a smooth surface than over a rough surface?
No, greater force is typically needed to move an object over a rough surface compared to a smooth surface. This is because the irregularities on a rough surface create more friction, making it harder to overcome resistance and move the object. Smooth surfaces offer less resistance to movement.
What surface would have the largest frictional force to resist the motion of a wooden block?
A rough surface with a lot of friction, like sandpaper or a rubber surface, would create the largest frictional force to resist the motion of a wooden block. Smooth surfaces have less friction and would not resist the motion as much.

What things control how much friction is present?
how hard you press and how smooth a surface is

Do snails move faster on rough surfaces or smooth surfaces?
Snails move faster on rough objects as the sticky liquid they use for locomotion gets good friction and helps it to move. But on rough surfaces, the frictional force is much less and the snail can hardly move.
What type of surfaces might cause a toy car to roll faster or slower?
Faster: Surfaces with less friction (smooth) ;slanted surfaces Slower: Surfaces with more friction (sticky surfaces, rough surfaces), uphill surfaces Of course a slanted surface with too much friction will also make the car slower.
How much friction is in cardboard?
Cardboard generally has low friction due to its smooth surface. However, the amount of friction can vary depending on the specific texture and condition of the cardboard.
Why does rubbing of a matchstick on a rough surface lights up?
The rough surface causes a lot of friction when the matchstick rubs against it. Friction causes heat (try this for yourself by rubbing the palms of your hands together- they feel hot. Then consider how smooth our skin is in comparison to the rough surface, so you appreciate how much heat it generated.) The heat causes the wood of the matchstick to set alight. Actually, the head of the matchstick is coated in a more flammable substance (phosphorus), which makes lighting even easier.
Why does rubber generate so much friction?
Rubber induces high friction because of its high coefficient of friction. The surface of rubber is rough and elastic, allowing it to deform and grip the surface it comes in contact with, resulting in increased friction. Additionally, the intermolecular forces between the rubber and the other surface further enhance the friction generated.
How will different surfaces affect the speed of a roller skate on an incline plane?
It depends on its roughness of the surface. The roughness on the surfaces will tell you how much friction will be acting. It is believed that the friction is caused by the interaction of the particles at sub-atomic level. The greater the interaction between the particles, the greater the friction. The more rough the surface, the less area will interact with both surfaces. Different surfaces, will have different friction coefficients, which decide if the roller skate will slip or not slip.
