# Examples Of Rolling Friction

Rolling friction is the force that resists the motion of a round object rolling over a surface. When you push a box across a concrete floor, you have to keep pushing it with some force, because there is some friction between the box and the floor. The friction keeps trying to drag the box back to where it started from. However, if the box had wheels on it, then you could push it across the floor much more easily. The friction between the wheels and the floor would be only rolling friction, and this is less than sliding friction

## Examples Of Rolling Friction

### Rolling friction is the force that resists the motion of a round object rolling over a surface.

Rolling friction is the force that resists the motion of a round object rolling over a surface.

Rolling friction is less than sliding friction because it has both static and kinetic components. The static component is caused by sticking between the two surfaces, while the kinetic part is due to actual rolling motion.

### When you push a box across a concrete floor, you have to keep pushing it with some force, because there is some friction between the box and the floor.

When you push a box across a concrete floor, you have to keep pushing it with some force, because there is some friction between the box and the floor. The friction force is proportional to the normal force; in other words, if you apply more force to push the box across the floor (increased normal force), you’ll get more resistance from rolling friction. This relationship is expressed by Newton’s Second Law of Motion:

### The friction keeps trying to drag the box back to where it started from.

The friction keeps trying to drag the box back to where it started from. The box wants to be in equilibrium, so it tries its best to get back to where it started from.

### However, if the box had wheels on it, then you could push it across the floor much more easily.

However, if the box had wheels on it, then you could push it across the floor much more easily. If you were to study this situation in detail, you would find that wheels provide less friction than a flat surface does. This is because of their round shape and how it interacts with the ground. Wheels roll over an uneven surface as opposed to sliding over it like a flat object would do (see Figure 1).

### The friction between the wheels and the floor would be only rolling friction, and this is less than sliding friction.

The friction between the wheels and the floor would be only rolling friction, and this is less than sliding friction. Rolling friction is the force that resists the motion of a round object rolling over a surface. It’s caused by two surfaces moving against each other with one surface (usually) in contact with air or gas. A common example of this is when you walk across carpeting with your shoes on; it’s much easier to slide your feet than roll them across the fabric, even though both actions result in some resistance from contact between skin and carpet fibers.

Rolling Friction Examples:

• When you’re trying to push something heavy, such as a car out of mud or snow
• When you’re moving luggage around during travel
• When putting on socks or gloves

### When an object rolls on another object, less energy is used than when an object slides.

When an object rolls on another object, less energy is used than when an object slides.

For example, if you want to push a box across the floor, exerting a force on it will require more effort than rolling it. The same principle applies when moving a heavy furniture piece or other large objects. Rolling friction becomes especially important when considering energy consumption in machines such as automobiles and trains (see examples below).

### Closing

Rolling friction is the force that opposes a body as it rolls over another surface. It is caused by the two surfaces interacting with each other.

The main example of rolling friction you will see in everyday life is when a car or bicycle slows down when it rides over an inclined plane (commonly called a hill). In this case, rolling friction occurs because the wheels are not able to roll across the ground without slipping. The coefficient of friction between rubber and asphalt has been found to be around 0.6–0.7 on smooth surfaces and 0.5–0.6 on rough ones like sandpaper or ice! So if you want better traction for your bike tires, try using some sandpaper between them instead of just air pressure….
