How is kinetic friction a negative and positive thing on a car or moving object?

In a car Friction creates Energy losses that result is a loss of mechanical efficiency, and therefore lower gas mileage.
On the positive side friction in the Braking System transform energy of motion into HEAT, allowing the car to stop.

How is static friction and kinetic friction differ from each other?
They are different because static means "not in motion" and kinetic means "in motion". Kinetic friction means friction that is moving and static friction means friction that is not moving.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
What is static friction and kinetic friction?
Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between two objects that are moving relative to each other (eg: a desk sliding on the floor)
What is sliding kinetic friction?
Sliding kinetic friction is when two moving (kinetic) objects rub (slide) against each other, creating friction. Sliding friction creates heat, unlike rolling or fluid friction.
Diference between static and kinetic friction?
the static friction is the force of friction that keep an object at rest from movie and kinetic friction is the force of friction that tries to start a moving object
What effect does friction have on a moving body?
Friction converts kinetic energy into heat. The result is that the moving body slows down.
Does friction provide negative acceleration or positive acceleration?
Friction opposes motion. As long as you define the direction in which the object is moving to be positive, the acceleration due to friction will be negative. If you think about it, you start out with positive speed and friction decreases the speed, so adding friction subtracted from the speed. Note: Friction is counterintuitive when you start dealing with rolling without slipping. This answer doesn't address this.
The type of friction between two moving objects?
Kinetic
What is the friction between a rolling object and the surface it rolls called?
i think its kinetic. kinetic comes from the greek word kinema which means basically "moving" so if the object is moving, it only makes sense that the friction is kinetic
What is the friction between a rolling object and the surface it rolls on called?
i think its kinetic. kinetic comes from the greek word kinema which means basically "moving" so if the object is moving, it only makes sense that the friction is kinetic
Should one add static friction and kinetic friction together to find the total friction force?
No. You use whichever applies: if an object is at rest, you use static friction. If it is moving, you use kinetic friction.
What is an example of sliding kinetic friction?
a bicycle moving on a sidewalk.... i think
