The article explains the concept of force and its measurement. Force is defined as the push or pull exerted on an object, which can cause motion or deformation. The article discusses Newton’s and Hooke’s laws, which describe the behavior of bodies under stress. Newton’s laws of motion and Hooke’s law are fundamental in understanding and measuring force.
The unit of force, the Newton (N), is derived from the fundamental unit of mass, the kilogram (kg). By definition, one Newton is the force required to accelerate a one-kilogram mass at a rate of one meter per second squared. The article mentions that the kilogram is defined by a specific platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France, with a replica at the National Institute of Standards and Technology in the US.
In summary, the article provides an overview of force, its measurement, and the fundamental laws governing its application and measurement.
