How does surface area affect friction?
more rough surface more friction object have
Does the surface area of an object affect the amount of friction between the object and the surface?
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
What can affect the amount of friction on an object?
the weight of the object, what its outside consists of, the nature of the surface it resting on.
Will the speed of the object affect the amount of friction between object and the surface?
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
Does an objects weight affect the amount of friction between the object and the surface?
Yes. Double the weight and double the friction.
How do different weights affect friction?
Friction is a resistance force imparted on an object sliding across a surface where the force is directly proportional to the WEIGHT of the object. The heavier the object that is moving across the surface the higher the frictional forces.
Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
What 2 factors affect friction?
the smoothness othe surface the object is acting on, and direction its going in
How do surface affect friction?
friction
Is friction affected by the amount of surface that is touching?
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
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.
Factors that affect the amount of friction?
1.nature of the substance and the surface (roughness or smoothness). 2.mass of the object.
