# Why does the spinning of wheels move a car?

• hndalama
In summary, the spinning of wheels moves a car due to the principle of rotational motion and the friction created with the ground. The weight of a car affects the spinning of wheels by determining the amount of force needed to overcome friction. Different types of wheels can also impact the movement of a car, with larger circumference and different materials and treads affecting its grip. Cars have multiple wheels to evenly distribute weight, provide stability, and increase surface area for better traction and control. A car cannot move without wheels as the spinning motion is necessary for friction and propulsion.

## Homework Statement

why does the spinning of wheels move a car?

## The Attempt at a Solution

The wheels spin backwards pushing on the road, friction opposes this spinning motion. But why does this result in the car moving forward? friction can only increase to be equal and opposite the force of motion

Think this way,We can accelerate only the force that acts on our body ,system etc.When Car's wheels spin it creates a force which pushes the ground backward.So ground makes us move forward as the same amount.

## Why does the spinning of wheels move a car?

The spinning of wheels moves a car because of the principle of rotational motion. As the wheels spin, they create friction with the ground, which propels the car forward.

## How does the weight of a car affect the spinning of wheels?

The weight of a car affects the spinning of wheels because the weight determines how much force is needed to overcome friction. A heavier car requires more force to move, which means the wheels will have to spin faster to propel the car forward.

## Do different types of wheels affect the movement of a car?

Yes, different types of wheels can affect the movement of a car. Wheels with a larger circumference will cover more ground with each rotation, resulting in a faster movement. Additionally, the material and tread of the wheels can also impact the grip and therefore the movement of the car.

## Why do cars have multiple wheels?

Cars have multiple wheels to distribute the weight of the car evenly and provide stability. Having more wheels also increases the surface area in contact with the ground, which allows for better traction and control while driving.

## Can a car move without wheels?

No, a car cannot move without wheels. The spinning motion of the wheels is necessary to create the friction needed to propel the car forward. Without wheels, there is no way for the car to move on its own.
