How do you raise and lower frictional forces?
A rough surface like sandpaper will have more friction than a smooth surface. smoothing out a surface will reduce friction
How does an object move on a rough and on a smooth surface?
It is on smooth surfaces because the amount of friction is less.
What is the definition of a smooth surface?
In general, we can say a surface is smooth if it's lack of any "grip" or textural features presents no friction.
What types of weather cause friction on surfaces to decrease?
Colder temperatures can cause friction on surfaces to decrease as it can make surfaces more smooth and slippery. Rain or wet conditions can also reduce friction due to the presence of moisture on the surface. Additionally, icy or frosty conditions can lead to a decrease in friction as the ice or frost can create a slippery surface.
What factors that affecting friction?
Friction actually depends on the roughness or smoothness of the surfaces of the object. Even some smooth objects that we usually see everyday (ex. glass, mirrorr,etc.) aren't that smooth when magnified by strong microscopes. They still have rough surfaces therefore they can also have friction. Factors that affect friction: 1.) Adhesion 2.) Surface roughness 3.)The area of an object which is in contact with the surface. The larger the surface in contact, the greater friction. 4.)The texture of the surface and/or the object. The rougher/more uneven the surface/object, the greater the friction. 5.) The weight on the surface. The larger the weight, the greater the friction 6.)The angle of the surface. The greater the angle of the surface, the greater the friction.
What is it called to smooth a surface to reduce friction?
lubrication
How ball bearing reduce friction?
Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. The smoothness of the metal reduces the friction and the surface area.
How do you raise and lower frictional forces?
A rough surface like sandpaper will have more friction than a smooth surface. smoothing out a surface will reduce friction
What provides a smooth slippery surface over bones to help reduce friction?
cartilage
Why do use powder on a carom board?
the main reason for doing so is that the surface becomes smooth n in terms of science to reduce "friction" that wud exist between the board n the striker due to which it will move more swiftly with lee deployment of power..!!
Does sand paper reduce friction?
sand paper increases friction, that is to say that it is harder to slide something on sand paper than it is on a smooth surface.
Why some friction occur with seemingly smooth surface?
A smooth surface is not actually smooth; it may have many microscopic bumps on its surface.
What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Why is it difficult to strike a match on a smooth surface?
Heat necessary to lit a match comes from friction between match head and the surface. Smooth surface gives way less friction.
Name 3 common ways you may use to reduce friction?
Reduce contact surface in the direction of friction. Introduce lubrication. Reduce load acting upon the friction surface.
The speed of ball increases as it rolls down an inclinem What happens to its speed on a smooth horizontal surface?
It's speed will reduce to to friction by gravity.
Does streamlining produce more or less friction?
In general it means that there will be less surface friction on the material. On vehicles this can be done by reducing the impact area at the front and by integrating smooth curves for the air to follow. Surface polishing can also increase airflow and reduce friction.
