If you are thinking about driving your car down the road, you require friction between your tires and the road to do so. This is known as kinetic friction, and in classical physics, the equation is as follows:
f = mu*N
where mu is the coefficient of kinetic friction, N is the normal force (force acting perpendicular to the road by the road), and f is the force of friction acting parallel to the road at the point of contact with your tires.
Introduce a thin layer of ice to the road and the coefficient of kinetic friction between your tires and the road drops drastically (mu in the above equation). As a result, your car cannot efficiently convert the force from your engine to a friction force between your tires and the road leading to rotational movement. Depending on the structure of the snow, it will also variably drop the coefficient of kinetic friction.
This is why, if you are moving and hit a patch of ice, you may temporarily lose control because your car will be at the mercy of the surroundings and its momentum (or inertia) rather than the steering system (no friction means no response from the steering wheel). Alternatively, if the car is at rest, it will be difficult to start moving.
tl;dr
Ice or snow decrease the coefficient of static friction for a surface variably depending on structure. This will decrease the friction force between an object and the surface.
What else can I help you with?
Why is there no friction on concrete?
Because ice is very slippery and so you can slide while on concrete you wont be a be able to slide because its not slippery.
What is one situation that friction is useful?
Friction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction. When we move on ice, it becomes difficult to walk due to low friction of ice.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure foothold.
When a blade of ice skates melts the ice beneath it what does it reduce?
It reduces drag. *Drag meaning friction between the blade and the ice. That said, it takes an extreme amount of force to melt ice by means of applying pressure. Consider a glacier-- if ice melted under a small amount of pressure, a large glacier would start to melt under its own weight! We can then realize that figure skaters do not melt the ice under the blade my means of pressure. Basically, yes friction/drag WOULD be reduced if the ice beneath the blade melted, but the ice simply won't melt due to the weight of the skater alone.
What game requires little or no friction?
Curling. A kettle is slid across the ice. Team members brush the ice in front of the kettle to minimize friction.
When a car travels around a curve in the road helps to keep the car traveling in a curved path?
That force is simply the friction of the tires on the road. If the car was driving on a slippery ice surface, the friction might not be enough and the car would not make it around the sharp curve.
How could you increase friction on an icy road?
you could place salt on the icy areas to increase friction because the ice would began to melt.
How could you increase the friction on an iced covered sidewalk or icy road?
Pour sand over the ice.
What has more friction road with gravel or road with ice or plain road?
A road with ice will have more friction than a road with gravel or a plain road. The presence of ice reduces the grip between tires and the road surface, resulting in decreased friction and potentially hazardous driving conditions. Gravel can also reduce friction compared to a plain road, but typically not as significantly as ice.
Which surface would you slide further on-road covered in ice or straw?
You would slide further on ice because it has a lower coefficient of friction compared to straw. Ice offers less resistance, allowing for smoother sliding and covering a greater distance compared to straw, which provides more friction and slows down movement.
Think of a pair of sliding objects where there would be a little friction think of two more where there would be a friction what are they?
Sex has a friction when people go up and down and up and down and pole dancing does.
Does snow increases friction?
Yes, snow can increase friction because it creates a layer of resistance between surfaces. The texture of snow can provide traction and increase the coefficient of friction, especially when compared to smoother surfaces like ice. However, snow can also decrease friction if it becomes compacted and turns into ice.
How much friction would an ice skater make?
An ice skater would make very little friction on ice due to the low coefficient of friction between the ice and the blades of the skates. This allows the skater to glide smoothly across the ice with minimal resistance.
Does surface type affect the force of friction?
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
Why do you need friction when you drive?
Friction between the tires and the road surface is necessary for a vehicle to accelerate, brake, and steer effectively. Without sufficient friction, the tires would not be able to grip the road, leading to loss of control and reduced ability to maneuver the vehicle.
When driving on a slippery surface such as snow or ice you should?
Put some sand on it to increase friction!
Why is sand put on ice?
Sand is often put on ice to improve traction and reduce the risk of slipping. The rough texture of sand creates friction between the ice and footwear or tires, helping to provide more grip and increase traction for safer travel on slippery surfaces.
Why would a car skid on a road?
The car skids less on a dry road due to greater friction between the tires and the alspahlt. Surfaces coated with water and ice have a lower coefficient of riction.
