How does a car increases and decreases friction?
To increase friction, the car goes faster so that the air resistance becomes greater. To decrease friction the car goes slower to decrease the air resistance acting on the car. Hope that helped:)
Can speed affect friction force?
Actually, friction does depend on velocity. If you stop your car you have to ease up on the brakes as you slow down because friction increases as you slow down. This effect has been observed for objects travelling at bullet velocities. Friction decrease as speed increases.
Why is important to reduce friction in a car engine?
Friction has two unpleasant effects: 1) it increases wear and tear, 2) it wastes energy.
What are the factors which affect the force of friction?
Friction equals the coefficient of friction times the normal force. Friction increases as the roughness of the materials increases. It also increases as the force pushing the materials together increases.
Does friction increases as rotation increases?
No. Friction is a function of Normal Force and the friction coefficient, nothing else.
Reducing friction in a machine increases or decreases?
Deceasing friction increases efficiency and reduces heat loss.
Does oil increases friction?
No.

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.
How friction increased?
With increased surface areas in contact, friction increases.
What happens if the net force on an object increases?
The amount of friction increases.
Why does the pressure of an tire increase if the automobile is driven for a while?
The air in the tire is becoming heated due to the tires friction on the road surface. Heated air increases the pressure in the tire
