Roads have rough surfaces because it cause more friction which a) slows down the car and b) because it stops the car swerving as much.
Machined surface is more rough.
the Romans invented the road
Roadways are built with spaces, or gaps, to accommodate expansion and contraction caused by temperature changes. These spaces, often referred to as expansion joints, help prevent cracking and structural damage due to thermal stress. Additionally, they allow for drainage and reduce the risk of water accumulation, which can weaken the road surface. Proper spacing is essential for maintaining the longevity and safety of the roadway.
It depends on the surface finish of the workpiece. For machined surface a magnetic base dial indicator is used. For rough or un-machined surfaces a surface gauge is used.
The weight of your body presses the shoe against the ground. Then as you walk on rough surfaces, little-by-little, the sole is scraped away. And that hole is where the sole is in contact with the rough surface for the longest amount of time.
roadways is very important for transportation.
The rough endoplasmic reticulum has ribosomes on its surface. This is what make is "rough"
Smooth surface
The rough surface is better than the smooth surface for the frictional force to act.
A rough and unpolished surface is called "unrefined" or "coarse."
The Rough Endoplasmic Reticulum (Rough ER) has ribosomes on its surface.
A basketball will roll faster on a smooth surface due to less friction compared to a rough surface. The rough surface creates more resistance, slowing down the ball's movement.
when light hits a rough surface it scattters.
The moon's surface is rough - due to numerous impacts from meteorites
no zinc is not rough it's surface is smooth
The force is greater on a rough surface compared to a smooth surface, due to the increased friction between the surfaces. The rough surface provides more resistance to motion, requiring more force to overcome the friction.
Reflection of light from a rough surface is known as "Diffused" or "Irregular" reflection, because the light rays are barely seen after the reflection of light from a rough surface.
