When is friction necessary for some type of movement to occur?

If a ball slides down a frictionless hill there will be no rotation of the ball. But with friction the ball will both translate and rotate down the hill.

Why does some friction occur with seemingly smoth surfaces?
Some friction will occur with seemingly smooth surfaces because at a molecular level, nothing is smooth.
What are some examples of car friction?
The movement of the car through the air.
Why does some friction occur on smooth surfaces?
Some friction will occur on smooth surfaces because even the smoothest of surfaces isn't completely smooth. There are bumps and cracks on the face of the surface when "zooming in" to a microscopic level.
Why friction is a necessary evil?
because we cant walk , hold articles , we cant write and the construction of house is impossible. but there are some disadvantages in friction.
How is wind energy lost?
Whenever there is movement, some energy is invariably lost due to friction.
Why does some friction occur with seeminly smooth surface?
Even though the surface appears smooth.at the microscopic level the surface has some peaks and cracks .when it slides over any other surface friction occurs. the seemingly smooth surface has some friction.
Why does some friction occur with a seemingly smooth surface?
I don't know... but everyone my heart is broken by a guy I like
What do you understand by limiting force of friction?
That it limits movement - that it doesn't let you, or some device, move around quickly.
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.
Why some friction occur with seemingly smooth surface?
A smooth surface is not actually smooth; it may have many microscopic bumps on its surface.
Why is hard engineering necessary at some parts of the coast?
to maintain its properties and form to reduce the friction and deformation in increasing temperature and pressure.
When is friction necessary?
Friction slows something down, so you'll need it when you drive the car (the brakes apply friction to the tires and you stop) and when you hold onto something (your hands apply friction to a credit card, thus enabling you to hold it), among others. You don't need it in some machinery (lubricants and bearings), among others.
