Friction and cars (or any traveling thing)

In summary, it is not possible for a traveling toy car with 1kg of mass and a maximum friction force of 1N to have an acceleration of >1m/s^2 on a flat surface without an incline. This is because the only force propelling the car is friction between the tires and the road, and any attempt to apply a higher force will result in slipping and less propelling force. The only way to achieve a higher acceleration would be to have a rocket engine in the trunk.

lets take the situation of a traveling toy car with 1kg of mass...
If the maximum force of friction between the car and the road is, let's say, 1N, then is it possible for the car to have >1m/s^2 acceleration?

Is there an incline?

no just a flat surface

Hey
I think that is possible
because you said that
m=1 Kg
max friction force=1N
okay, see when the car will move it's equation will be
x comonent
F(applied force)-f(friction force)=ma
if you raise your applied force you will get acceleration greater than 1m/s2

the only force propelling a car is friction between tires and the road, which will determine the maximum acceleration (and deceleration) if you want to neglect drag; trying to apply any higher force will result in slipping and actually less propelling force because the tires will go from static to dynamic friction.
The answer to the original post is no, it not possible (unless you carry a rocket engine in the trunk)

Related to Friction and cars (or any traveling thing)

What is friction?

Friction is a force that resists the motion of an object when it comes into contact with another object or surface. It is caused by the roughness and irregularities on the surfaces of the objects.

How does friction affect cars?

Friction plays a crucial role in the movement of cars. It helps the car tires grip the road, allowing the car to move forward. However, too much friction can cause the car to slow down or even skid.

What are some ways to reduce friction in cars?

One way to reduce friction in cars is by using lubricants such as oil or grease. These substances create a slippery layer between two surfaces, reducing the amount of friction. Another way is by using smooth and aerodynamic designs for cars to reduce air resistance, which can also cause friction.

How does friction affect fuel efficiency in cars?

Friction can significantly impact the fuel efficiency of cars. When there is high friction between the tires and the road, the engine has to work harder to move the car, leading to more fuel consumption. This is why it is essential to keep car tires properly inflated and replace them when they are worn out.

Can friction be beneficial for cars?

Yes, friction can be beneficial for cars in certain situations. For example, the friction between the brake pads and the wheels helps to slow down and stop the car. Friction also allows the car tires to grip the road, providing stability and control while driving.
