Question

explain the application of rolling friction in daily life ?​

Answer 1

Shape of wheel

The type of surface on which the wheel is rolling

Any movement of the surface or below the surface

Original speed of the wheel

Diameter of the wheel

Amount of pressure on the wheel

Adhesion of the surface

Any amount of sliding that occurs in addition to the rolling motion

Deformation of object or of surface

Over inflation of tires

Micro-sliding

Thickness of tread on tires

Shape of tread on tires

Material that wheel or ball is made of

Any ball or wheel has rolling friction when rolled on a surface. Some examples of items that have rolling friction are:

Truck tires

Ball bearings

Bike wheels

Soccer ball, basketball, or baseball

Car tires

Skateboard tires

Railroad steel wheels

Bowling ball

Examples of Rolling Friction:

1. Winter Fun

There are a variety of ways that rolling friction has an impact on winter activities. For everything from recreational events like skiing and sledding to elite-caliber sports like Olympic bobsledding, curling, figure skating, speed skating, and hockey, rolling friction plays an important part in the outcome.

As the object-the sled, the skates, the rock, or anything else-moves, friction heats the surface of the object that comes in contact with the snow or ice. The snow or ice is actually momentarily melted and then refrozen as the object moves across its surface. This factor is significant enough that it must be taken into account when planning a competition strategy, but can also just impact a person's enjoyment of the great outdoors during the winter months.

2. Vehicles

A lot of factors will impact the amount of rolling friction that occurs with a moving vehicle. The size, weight, shape, and surface area of the wheels will all play a part, as well as the surface and the path the road or track takes. An eighteen-wheeler carrying a heavy load will have greater rolling friction than a compact car, for example, and a train going around a curved track will have greater rolling friction than a train that is traveling on a straight track.

3. Toys

Skateboards, roller skates, and in-line skates all experience rolling friction when they're in use, but the degrees of friction they experience are different due to their size, shape, wheel alignment, and weight distribution. A skateboard supports the body weight of its human rider on four wheels instead of rollers skates' eight wheels, so it will experience greater rolling friction and come to a stop sooner than if its rider-the same person-was moving on roller skates. Roller skates will experience greater rolling friction than in-line skates, though, due to the wheel placement and the fact that the roller skates have a greater surface are coming in contact with the road.

4. More Toys

When playing any sport that involves a ball-like a soccer ball, baseball, or bowling ball, for example-rolling friction is a determining factor that must be taken into consideration when plotting the next move. Soccer players have to account for factors like rain water or dew on the playing field, which will decrease the amount of rolling friction as they kick the ball to other players, whereas bowlers have to account for grease and other grimy content coating the bowling ball or the lane when they throw.
