Relationship between information and force

The Meaning of Force

relationship between information and force

The Task Force reports to the ACWIthat operates under the Federal Advisory Advisory Committee on Water Information Subgroup Guidance In addition to the with the private sector and the appropriate relationship with the private sector. With these new weapons, distinct nuclear concepts such as the force In particular, the relationship between information and energy used in applying force has. The second law of motion explains the relationship between force, mass, and acceleration. The relationship of force to mass and acceleration can be expressed.

To fully describe the force acting upon an object, you must describe both the magnitude size or numerical value and the direction.

Thus, 10 Newton is not a full description of the force acting upon an object. In contrast, 10 Newton, downward is a complete description of the force acting upon an object; both the magnitude 10 Newton and the direction downward are given.

The Meaning of Force

Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. Such vector diagrams were introduced in an earlier unit and are used throughout the study of physics. The size of the arrow is reflective of the magnitude of the force and the direction of the arrow reveals the direction that the force is acting.

Such diagrams are known as free-body diagrams and are discussed later in this lesson. Furthermore, because forces are vectors, the effect of an individual force upon an object is often canceled by the effect of another force. For example, the effect of a Newton upward force acting upon a book is canceled by the effect of a Newton downward force acting upon the book.

Newton's Second Law

In such instances, it is said that the two individual forces balance each other; there would be no unbalanced force acting upon the book. Other situations could be imagined in which two of the individual vector forces cancel each other "balance"yet a third individual force exists that is not balanced by another force. In part this was due to an incomplete understanding of the sometimes non-obvious force of frictionand a consequently inadequate view of the nature of natural motion.

Most of the previous misunderstandings about motion and force were eventually corrected by Galileo Galilei and Sir Isaac Newton. With his mathematical insight, Sir Isaac Newton formulated laws of motion that were not improved for nearly three hundred years.

With modern insights into quantum mechanics and technology that can accelerate particles close to the speed of light, particle physics has devised a Standard Model to describe forces between particles smaller than atoms.

The Standard Model predicts that exchanged particles called gauge bosons are the fundamental means by which forces are emitted and absorbed.

Only four main interactions are known: Aristotelian physics and Theory of impetus Aristotle famously described a force as anything that causes an object to undergo "unnatural motion" Since antiquity the concept of force has been recognized as integral to the functioning of each of the simple machines. The mechanical advantage given by a simple machine allowed for less force to be used in exchange for that force acting over a greater distance for the same amount of work.

Analysis of the characteristics of forces ultimately culminated in the work of Archimedes who was especially famous for formulating a treatment of buoyant forces inherent in fluids.

In Aristotle's view, the terrestrial sphere contained four elements that come to rest at different "natural places" therein. Aristotle believed that motionless objects on Earth, those composed mostly of the elements earth and water, to be in their natural place on the ground and that they will stay that way if left alone.

He distinguished between the innate tendency of objects to find their "natural place" e.

Motion – The Physics Hypertextbook

The place where the archer moves the projectile was at the start of the flight, and while the projectile sailed through the air, no discernible efficient cause acts on it.

Aristotle was aware of this problem and proposed that the air displaced through the projectile's path carries the projectile to its target. This explanation demands a continuum like air for change of place in general. The shortcomings of Aristotelian physics would not be fully corrected until the 17th century work of Galileo Galileiwho was influenced by the late medieval idea that objects in forced motion carried an innate force of impetus. Galileo constructed an experiment in which stones and cannonballs were both rolled down an incline to disprove the Aristotelian theory of motion.
