The science of describing the motion of objects using words, diagrams, numbers, graphs, and equations.

sometimes referred to as the law of inertia, describes the influence of a balance of forces upon the subsequent movement of an object.

depict a vector by use of an arrow drawn to scale in a specific direction.

A commonly used term in sports.

The stored energy of position possessed by an object.

quantities that are fully described by a magnitude (or numerical value) alone.

acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

A variety of mathematical operations can be performed with and upon vectors.

These concepts are merely an outgrowth of Newton's second law as discussed in an earlier unit.

The energy of motion.

quantities that are fully described by both a magnitude and a direction.

when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.

a useful method for determining the result of adding two (and only two) vectors that make a right angle to each other.

There are several real-world applications of these phenomena. One example is the use of air bags in automobiles. Air bags are used in automobiles because they are able to minimize the effect of the force on an object involved in a collision.

The energy acquired by the objects upon which work is done

a scalar quantity that refers to "how much ground an object has covered" during its motion.

push or pull upon an object resulting from the object's interaction with another object.

An object upon which the only force acting is gravity. There are a variety of examples of projectiles.

an interaction between two objects that have made contact (usually) with each other.

The standard metric unit of power

a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

those types of forces that result even when the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite their physical separation.

The vector sum of all the forces that act upon an object.

One of the most powerful laws in physics is the law of momentum conservation. The law of momentum conservation can be stated as follows.

The quantity work has to do with a force causing a displacement. Work has nothing to do with the amount of time that this force acts to cause the displacement.
