How surface influences the amount of friction there is?
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
How can a wet surface affect friction?
Water can make a flat surface more slippery, which will decrease the amount of friction
What surface uses the least amount of friction?
wet surfaces like tiles have the least amount oof friction
What is the relationship between the type and the amount of friction?
The more uneven the surface, the more friction there is.
Is it true that weight affects the amount of friction between the object and a surface?
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
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.
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 two factors depend on the amount of friction?
gravity and how rough the surface is
Is the amount of friction greater between rough surfaces or smooth and Why?
Rough surfaces, the rougher the surface, the greater the friction.
Does an objects weight affect the amount of friction between the object and the surface?
Yes. Double the weight and double the friction.
Does the ramp surface effect the speed of a car?
yes, of course different surface different amount of friction
What is the effect of friction of a speed of a toy car?
Friction can have a slowing effect on the speed of a toy car. When the wheels of the car come in contact with the surface it is moving on, friction between the two surfaces can cause resistance, making it harder for the car to maintain its speed. The amount of friction depends on factors such as the type of surface and the weight of the car.
