What is the advantage of rolling wheels over sliding wheels in an emergency?

Rolling wheels have more traction than sliding wheels. Thus you have more control.
To illustrate; If you were in a turn and either locked the brakes or accelerated too fast the rear wheels loose traction and the rear of the car starts to pass the front of the car.

Why do workers have to push heavy boxes on carts with wheels?
rolling friction is less than sliding friction
What are advantages of wheel?
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
What are examples of sliding friction and static friction?
Static: A cars wheels (while car and wheels are stopped, or while car is moving and wheels are rolling), a doorstop, a rock on a hill (not sliding down) and the force keeping a nail in some wood. Sliding: A cars wheels (during burnouts or when brakes are applied too hard and the car skids), dragging a computer mouse along a table, Ice skaters blades and a drink slid down the bar to you.
Which is an example of sliding friction a cars wheels rolling down the road a bird flying through the air a child applying the brakes on his bike a bowling ball rolling down a lan?
child applying brakes
Why wheels help things move faster?
Because rolling friction is usually less than sliding friction. A cart will move easier than a sled.
What are the 3 kinds of friction describe each?
sliding friction is like sliding a desk without wheels across a floor since its sliding and if there a large amount of weight involved it will be harter to over come the friction , rooling friction is like a skateboard rooling down the street for rooling friction the object NEEDS to have wheels or it wouldn't be rooling friction,and fluid friction is like droping a ball through air since air has water particles and counts for fluid friction.
How difficult is it to change emergency brakes to front wheels?
There are no emergency brakes on the front wheels of vehicles.
What are the three types of fricton?
The three types of friction are static, sliding and rolling I'll use a car to illustrate these three types. If you try to push your car sideways (push on the passenger or driver's door) and it won't move, the force between the tires and the driveway ( or whatever surface the car is on) that prevents the car from moving is static friction. If you're driving down the highway and apply the brakes but not enough to stop the wheels from rolling, the force between the tiers and the highway that is slowing the car is rolling friction. If you slam on the brakes and lock the wheels so they are sliding/skidding down the highway the force between the tires and the highway that will eventually bring the car to a stop is sliding friction.

Give a long introduction of friction and its types?
the four types of friction are static friction,sliding friction,rolling friction,and fluid friction Static friction is friction between two solid objects that are not moving relative to each other. Fluid friction is with any kind of liquid or glass. sliding friction is when a surface slides on another surface. Rolling friction is when you are moving with wheels.
Do the wheels on the stand lock to hold it from rolling around?
There are four wheels to Bowflex-SelectTech-Dumbbell-Stand and two wheels can be independently locked with help of latch to prevent the stand from rolling
What is the wheels purpose?
To keep you rolling smoothly.
