Want this question answered?
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.
Water can make a flat surface more slippery, which will decrease the amount of friction
wet surfaces like tiles have the least amount oof friction
The more uneven the surface, the more friction there is.
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
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
gravity and how rough the surface is
Rough surfaces, the rougher the surface, the greater the friction.
Yes. Double the weight and double the friction.
yes, of course different surface different amount of friction
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.
