Why do roads shine?
Roads appear to shine when wet because of the reflection and refraction of light on the smooth surface of the water. This creates a glossy effect that makes the road appear shiny.
Which type of roads has the most friction?
Rough asphalt roads typically have the most friction due to the texture of the surface, which provides better traction for vehicles. Smooth roads, such as concrete or tarmac, may have less friction and can be more slippery, especially when wet.
Why do Icy roads have less friction then dry roads?
Icy roads have less friction than dry roads because ice is a smooth and slippery surface, making it difficult for tires to gain traction. The lack of friction between the tires and the icy surface reduces the ability of the vehicle to brake, accelerate, and turn effectively, leading to increased risk of accidents. Dry roads, on the other hand, provide better traction for tires due to the rougher surface, allowing for better control and maneuverability.
When high friction is not useful in daily life?
High friction is not useful in situations where smooth, effortless movement is desired, such as when driving on icy roads or pushing a heavy object along a smooth surface. Excessive friction can cause wear and tear on surfaces, increase energy consumption, and make tasks more difficult to perform.
How does surface of car affect car speed?
If the surface is rough/bumpy , the vehicle cant safely go as fast as it can on a smooth road. Also if the car is bouncing, it's aerodynamics will be disturbed causing more drag. Ground clearance also has to be increased on rough roads, causing more drag.
A tarry mixture used to make a smooth hard surface on roads and paths?
Asphalt. Macadam is another common name for the process. To Macadamize something is to pave it with asphalt.
How where roman roads built?
they were built with smooth rocks on the to top. Then on the side there were paths for people when solider were marching down the road.
Place where roads or paths meet?
Intersect
Why do roads shine?
Roads appear to shine when wet because of the reflection and refraction of light on the smooth surface of the water. This creates a glossy effect that makes the road appear shiny.
Is tarmac an impermeable rock?
Tarmac is not a rock; it is a man-made material used for surfacing roads, driveways, and parking lots. It is a mixture of asphalt and aggregate materials that form a smooth and durable surface. Tarmac is not impermeable and can allow some water to pass through its surface.
Why are smooth tires bad for driving on wet roads?
Smooth tires are bad for driving on wet roads because they have less traction and grip on the slippery surface, increasing the risk of skidding and losing control of the vehicle. The lack of tread patterns on smooth tires also makes it harder for water to be dispersed, leading to a higher chance of hydroplaning.
How did travellers find their way before useful maps?
roads and paths

Which type of roads has the most friction?

Was there roads in the Persian Empire?
The question is "WERE there roads in the Persian empire". The simple answer is no, the Persians only had dirt paths they travelled on but not "roads" by definition being a paved path. The Romans invented roads.
What causes shimmy when going over bumpy roads?
Inadequate shocks, and or suspension components that are usually on passenger cars that aren't designed to travel on any surface other than a smooth, paved surface.
What do people walk on?
People typically walk on surfaces like sidewalks, roads, grass, dirt paths, or floors indoors. The specific surface depends on the setting and environment in which they are walking.
