Everything a car does is to over come friction.
When the engine runs, it has to move against all the parts rubbing together inside.
When it rolls down the road all the bearings, gears, tire and such cause friction.
When it moves through the air that is a type of friction.
Anything you do to reduce the fiction levels, the less energy it uses.

How does mass effect efficiency?
The mass affects the efficiency of an object. It adds more weight, which causes more friction. More friction=less efficiency
What is one harmfull way friction affects a car?
Creates heat in the engine (friction of moving parts creates heat) Reduces efficiency (friction in the drivetrain, as well as air resistance, slows the car down) Causes the tires to wear out (friction between the road and the rubber causes the rubber to wear)
What affects the speed of a rolling car?
Friction, gravity, wind resistence(form of friction)
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
What does reducing friction increase?
Efficiency Efficiency

What is one way friction affects a car?

What is the helpful way friction affects a car?
By using kinetic friction
How do friction affect a car when it stop?
it affects it by the contact with the car
What affects the speed of a rolling car?
Friction, gravity, wind resistence(form of friction)
Does the texture of a ramp matter when you roll a car down?
Yes, it affects the friction.

What does reducing friction increase?
Efficiency Efficiency
What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
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 does friction effect effiecency?
If there is more friction with a machine, efficiency is less.
