What’s centrifugal force?

Centrifugal force is the outward pressure around an object as it rotates. It can be explained by Newton’s law of inertia, but not all aspects are understood. It is used in everyday life, such as in clothes dryers and medical centrifuges. Understanding is not necessary to benefit from it.

Centrifugal force is the force describing the outward pressure that occurs around an object as it rotates about a central point. His definition is based on a Latin phrase meaning “to escape from the center”, an accurate description based on what is observed. There are some physicists who argue that there are no real centrifugal forces, that the reaction of an object to that force can be explained by other means.

A possible explanation for the centrifugal force lies in Newton’s law of inertia. This law states that an object in uniform motion tends to stay in the same motion unless there is pressure exerted by an external force. For example, a ball being spun on a string would tend to go in a straight line were it not for the string and the force the string exerts on the ball. Thus, the ball, instead of going in a straight line, makes a circular motion around the center of the pin.

This explanation, because it is easily understood, does not explain all aspects of centrifugal force. For example, why does the force still exist when there is no rope? In these cases, there is likely still an external force exerting pressure on the object, preventing it from going in a straight line. It is likely to include a cylinder.

While the concept is not easily understood, the benefits of what many people call centrifugal force are used for the benefit of mankind. For example, centrifugal force is what dries clothes in a clothes dryer. Along with the heat used, the dryer also spins the clothes, just like a washing machine does, to get most of the water out before the dryer finishes the job.

The medical community often uses a specific device to create a centrifugal force, something commonly referred to as a centrifuge. This spins blood samples to separate solids from liquids, which makes it better for detecting certain conditions. As the blood spins, the heavier parts tend to settle towards the bottom of the vial.

Ultimately, centrifugal force can still be explained. However, the nice thing about the phenomenon is that you don’t have to fully understand it to take advantage of it. The effects are evident and the benefits derived from strength are numerous.
