What else can I help you with?
Does friction increase or decrease when the vehicles are on the road?
Friction between the tires and the road increases when vehicles are on the road. The friction helps the tires grip the road surface, allowing the vehicles to accelerate, decelerate, and corner effectively.
What is an example of not useful friction?
An example of not useful friction is the friction between the tires of a car and the road surface when trying to accelerate. This friction wastes energy in the form of heat and wears down both the tires and the road, without serving a beneficial purpose in this context.
What road conditions will cause friction to reduce?
Wet or icy road conditions can cause friction to reduce because surfaces become slippery, reducing the ability of tires to grip the road. Additionally, oil spills or loose gravel on the road can also decrease friction between the tires and the road surface.
What is the average coefficient of friction for a dry road?
The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.
How do you write an example of how friction can help and affect something?
Friction between the tires of a car and the road surface helps it to stay on the road and control its speed. However, excessive friction can cause the tires to wear out more quickly and decrease fuel efficiency.
What causes road wear?
umm the road, friction between your tires and the roads surface.
What forces created the screeching of tires?
Friction between the tire and the road surface

Is it true cars need friction to keep moving?
Yes, cars need friction between their tires and the road surface to accelerate, decelerate, and turn. Without friction, the tires would not be able to grip the road, leading to the car sliding or skidding uncontrollably.
What is friction when it stops tires?
Friction is the force that resists the motion of objects when they are in contact with each other. When tires stop moving, the friction between the tires and the road surface helps to bring the vehicle to a halt by creating a counter-force that opposes the forward motion of the tires.
Why do cars slide when braking?
Cars slide when braking because the friction between the tires and the road is not enough to stop the car's momentum. This lack of friction causes the tires to lose traction and slide instead of gripping the road surface.
Why is it more difficult to stop a boat in water than a bus on the road?
Because there is less friction between the hull and the water than there is between the road surface and the tires.
What is the relationship between friction and surface area of tires unusual?
The relationship between friction and surface area of tires is unusual because an increase in surface area typically leads to an increase in friction, but for tires, this is not always the case. Tires with wider surface areas may not always have higher friction, as other factors such as tire material, tread pattern, and road conditions also play a significant role in determining friction.
