Speed does not affect the force of friction.
Ff = μs Fn
My textbook says speed between two surfaces does not affect friction.
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.
Speed is a scalar (non-directional) representation of velocity. Friction affects the magnitude of both and the direction of velocity.
You may be thinking of drag instead of friction. Friction between the floor and your foot increases your speed.
No, friction is the force between to objects created by gravity.
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.
Friction and Gravitational forces
Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires
Friction decreases the speed of something rubbing against something else.
Yes it does. The more "rough" the texture is, the more friction there will be. This will cause a decrease in speed and acceleration.
Any and every object that's moving through air at speed is affected by air friction.
