Newton's Third Law of Motion Is Broken by Human Sperm and Algae

Description

Newton's third law of motion, which states that "for every action, there is an equal and opposite reaction," is a fundamental physics principle. Scientists have discovered an intriguing exception to this law in the area of biological swimmers, specifically human sperm. Researchers discovered that sperm can float by deforming their bodies in a way that does not cause a reaction from their environment, thereby violating Newton's law.

Contesting Newton's Law

Scientists evaluated data from human sperm cells and Chlamydomonas algae to get this ground-breaking finding. The researchers wanted to find instances of non-reciprocal mechanical interactions that defy Newton's third rule, which they termed "odd elasticity."

Flagella at Work

Flagella, which are hair-like appendages, are used by both sperm cells and Chlamydomonas algae to promote mobility. These flagella, which resemble tails, extend from the cells and allow the cells to change form in reaction to the surrounding fluid. They also do it in a non-reciprocal manner, which violates Newton's third law because they do not elicit an equal and opposite reaction from their surroundings.

The Role of Unusual Elasticity

While the elasticity of the flagellum does not fully explain how the cell moves, the concept of odd elasticity is critical. Cells with unusual elasticity can move their flagella with minimal energy consumption in their environment, which would normally impede their motion.

Enhancing Mobility

The capacity of a flagellum to wave without considerable energy loss increases with the cell's odd elasticity score or odd elastic modulus, according to the study. This improved ability defies physical restrictions and allows the cell to move more efficiently. Flagella are not specific to sperm and algae, implying that other rule-breaking cells or creatures may exist.

Application Possibilities

Understanding and classifying cells or organisms capable of non-reciprocal movement could have practical uses. The study, for example, proposes that this knowledge could be used to construct small, elastic robots capable of breaking Newton's third rule. This method has the potential to lead to future technological improvements.
