How does surface area affect friction?
more rough surface more friction object have
What three forces affect speed?
The three forces that affect speed are thrust (what propels the object forward), surface area (the smoothness and amount of area that comes in contact with the air, which can also be called friction), and drag.
Does an objects shape and speed affect friction?
Yes Shapes changes the friction because it changes the surface area among other things. speed affects it is the sense that the object would come in more contact with the air and so the faster it goes the more friction
What two factors influence the amount of friction?
The two factors on which friction depends are as follows 1. Area of contact 2. Mass of object
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.

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 are the different ways the lassen or minimize the effect of friction?
By reducing the contact surface area of the object and by applying the lubricant between the two contact surfaces lassens or minimizes the effect of friction.

Does fluid friction vary with speed and area contact?
Fluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
What is the friction between around surface and another object?
Because a round object has less surface area in contact with the solid surface it's being propelled upon, there is less friction between the two objects and the sphere will travel farther on that surface than a flat object (lots of contact....lots of friction....and therefore, resistance to motion) due to the difference in friction.
What happened to the coefficients of friction as the surface area of the contact increased?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.

Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.
