Why does a concrete path produce greater friction then a lino floor?
A concrete path produces greater friction that a linoleum floor because its surface is rougher. This allows more surface area to contact an object moving along the path.
What are 5 types of friction?
1. Static2. Sliding3. Rolling4. Air5. Fluid
As soon as an object starts moving what replaces static friction?
Kinetic Friction replaces Static Friction when an object is in motion.
Without friction there would be?
NO friction
How are air resistance and friction alike?
Air resistance is a type of fluid friction (along with water resistance) and is therefore is a type of friction.
Coefficient of friction between concrete and concrete?
1
Why is that an automobile can travel faster on a concrete road than on desert?
Less resistance/friction on concrete.
Why an automobile can travel faster on a concrete road than on a desert?
Less resistance/friction on concrete.
What creates more friction, concrete or grass?
Grass. This is because carpet (grass or soil) has more friction than a smooth surface like tile (concrete).
Is concrete has a better coefficient of friction than asphalt?
Yes, concrete typically has a higher coefficient of friction than asphalt due to its rougher texture. This makes concrete surfaces less slippery and provides better traction for vehicles and pedestrians.
Why don't you go as fast on the grass as you do on concrete on a scooter?
The grass has more friction than the concrete, so the scooter doesn't go as fast
Why does a concrete path produce greater friction then a lino floor?
A concrete path produces greater friction that a linoleum floor because its surface is rougher. This allows more surface area to contact an object moving along the path.
What happens when concrete is vibrated?
internal friction between the aggregate particles is temporarily broken
What 2 surfaces would have the highest coefficient or friction?
Two surfaces with high coefficients of friction are rubber on concrete and sandpaper on wood. These surfaces have rough textures that increase friction and resistance to sliding.
Why is it easier to push a crate over a smooth concrete sidewalk than over grass?
There's less friction over a smooth concrete sidewalk
Why do we slide on ice but not on concrete?
We slide on ice because its surface is smooth and has a low coefficient of friction, which allows for easier movement over it. When we apply pressure, ice can slightly melt at the surface, creating a thin layer of water that further reduces friction. In contrast, concrete has a rougher texture and a higher coefficient of friction, making it more difficult to slide on. This difference in surface properties explains why sliding occurs on ice but not on concrete.
Why do some car parks have grooves on concrete grounds?
Because the grooves increase yhe friction
