What would happen if a car had no friction?
It would not be able to move. The push of the engine driving the car forward depends on friction between the tyres and the road. If something else started it moving, the brakes couldn't work to stop it.
How does the mass of a toy car affect its speed going down a ramp?
The weight of the car will cause the force of gravity to push it down with seemingly more force than the lighter car. And so this would make the car go faster down a slanted surface, which is the ramp.
Why increase friction?
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
Why is friction necessary to make a car move?
Because if there is no friction between the wheels and the asphalt the car would simply spin out. Unable to move at all on a friction-less surface. In fact, it's so important racecars have upsidedown wings to push the car into the ground to get better friction. Which when we're talking about car wheels is also called traction.
What force causes a car to stop?
Rolling friction causes a car to stop.
How do you push a car uphill?
Find a hill and stop the car, using a friend to steer the car you get behind and push.....
How do you stop on a stick car?
push the break
Why will a toy car stop when you push it?
No, because you are pushing it.
At an intersection where there is a two way stop who would be at fault in an accident if the car that was required to stop and a car crossing that is not required to stop collide in the intersection?
It would be the car that was required to stop. That car should make sure it is clear before going through the intersection.
What is the frictional force required to stop a car?
The same amount of force required to push the car.
What make the car go when you push the car?
Force and momentum
What would make your 1995 blazer just stop running?
a car bomb
What would make your car to escelerate when you are tying to stop?
you get your pedals mixed up
How can you make an car move with no battery?
You can push it
Would old oil make a car cut off?
no old oil will not stop a car beacause at least the car has oil
