Newton

English mathematician and physicist who is widely credited as one of the most influential scientists of all time.

Contributions to Science

Newton made significant contributions to various fields of science, including:

Mathematics:

• Developed the calculus, a fundamental tool in modern mathematics.
• Formulated the binomial theorem, which expands a binomial raised to a positive integer power.

Physics:

• Proposed the three laws of motion, which describe the behavior of objects in motion.
• Developed the law of universal gravitation, explaining the force of attraction between objects with mass.

Optics:

• Conducted experiments with light and prisms, leading to the understanding of the composition of white light.
• Developed the reflecting telescope, an improvement over refracting telescopes.

Principia Mathematica

Newton’s most famous work, “Philosophiae Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy), published in 1687, is considered a groundbreaking scientific treatise.

It presents his laws of motion and universal gravitation, revolutionizing the understanding of the physical world.

Other Achievements

In addition to his scientific contributions, Newton also:

• Served as the Master of the Royal Mint, responsible for overseeing the production of coins.
• Conducted alchemical experiments and wrote extensively on religious topics.

Legacy

Newton’s work laid the foundation for classical mechanics and influenced subsequent scientific advancements.

His contributions continue to shape our understanding of the universe and inspire scientific inquiry.

Recognition and Honors

Newton received numerous accolades and honors during his lifetime, including:

• Knighted by Queen Anne in 1705.
• Elected President of the Royal Society, a prestigious scientific academy, in 1703.

Isaac Newton’s profound impact on science and his enduring legacy as one of the greatest scientific minds in history solidify his position as a towering figure in the annals of human intellectual achievement.

Dyne

A dyne is a unit of force in the centimeter-gram-second (CGS) system of units. It is defined as the force required to accelerate a mass of one gram by one centimeter per second squared.

Symbol

The symbol for dyne is dyn.

$$1 dyn = 1 g \cdot cm/s^2$$

Where:

• g is the gram, the unit of mass in the CGS system.
• cm is the centimeter, the unit of length in the CGS system.
• s is the second, the unit of time in the CGS system.

History

The dyne was first defined in 1873 by the British Association for the Advancement of Science (BAAS). It was originally called the “absolute unit of force” and was defined as the force required to accelerate a mass of one pound by one foot per second squared.

In 1901, the BAAS adopted the CGS system of units and the dyne was redefined as the force required to accelerate a mass of one gram by one centimeter per second squared.

SI equivalent

The dyne is not a unit of force in the International System of Units (SI). The SI unit of force is the newton (N).

$$1 dyn = 10^{-5} N$$

Examples

Some examples of forces that are approximately equal to one dyne include:

• The force of gravity on a mass of one milligram.
• The force required to hold a one-gram mass against the Earth’s gravity.
• The force required to accelerate a one-gram mass by one centimeter per second squared.

Applications

The dyne is still used in some applications, particularly in the fields of physics and engineering. However, it is being increasingly replaced by the newton, which is the SI unit of force.

Relation between Newton and Dyne

Newton

• The newton (symbol: N) is the International System of Units (SI) derived unit of force.
• It is named after Sir Isaac Newton in recognition of his contributions to classical mechanics.
• One newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared in the direction of the applied force.

Dyne

• The dyne (symbol: dyn) is a unit of force in the centimeter-gram-second (CGS) system of units.
• It is defined as the force required to accelerate a mass of one gram at a rate of one centimeter per second squared in the direction of the applied force.

Conversion Between Newton and Dyne

• The relationship between newton and dyne can be derived from the definitions of both units.
• 1 newton (N) is equal to 100,000 dynes (dyn).

Summary

• The newton is the SI unit of force, while the dyne is a unit of force in the CGS system.
• 1 newton is equal to 100,000 dynes.

Relation Between Newton and Dyne FAQs

What is the relation between newton and dyne?

1 newton (N) is equal to 100,000 dynes (dyn).

How to convert newtons to dynes?

• To convert newtons to dynes, multiply the force in newtons by 100,000.

How to convert dynes to newtons?

• To convert dynes to newtons, divide the force in dynes by 100,000.

What is the difference between newton and dyne?

• Newton is an SI unit of force, while dyne is a CGS unit of force.
• Newton is a more commonly used unit of force than dyne.

When is it appropriate to use newtons and when is it appropriate to use dynes?

• Newtons are typically used to measure larger forces, such as the force of gravity or the force exerted by a car engine.
• Dynes are typically used to measure smaller forces, such as the force of friction or the force exerted by a spring.

Examples of forces in newtons and dynes

• 1 newton is equal to the force of gravity acting on a 1-kilogram mass.
• 1 dyne is equal to the force required to accelerate a 1-gram mass by 1 centimeter per second squared.

Conclusion

• Newton and dyne are both units of force, but they are used in different situations.
• Newtons are typically used to measure larger forces, while dynes are typically used to measure smaller forces.
