A newton (N) is the standard unit of force in the International System of Units (SI). It is named after the renowned physicist Sir Isaac Newton, who made significant contributions to the field of mechanics and the study of forces.

One newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg·m/s²).

In other words, when a force of one newton is applied to an object with a mass of one kilogram, it will cause that object to accelerate at a rate of one meter per second squared.

To put it in practical terms, one Newton is roughly equivalent to the force required to lift a small apple or a medium-sized tomato against the force of gravity on Earth.

Understanding the value of one newton is fundamental in various fields, including physics, engineering, and everyday activities. It provides a standardized way to quantify and compare forces, making it an essential concept in the study of motion and mechanics.
