Force is classified as a vector quantity because it is a quantity that has both direction and magnitude (numerical value). Force is measured by the standard metric unit known as the newton; one newton is equivalent to 1-kg/(m)(s)^{2}.
Know MoreForce is either a push or pull of an object, and can only occur as a result of an interaction between objects. To describe a force acting upon an object, it is necessary to describe the direction and magnitude of the force. In physics, it is common practice to represent forces in vector diagrams to illustrate all of the forces acting on an object. This visualization helps discern which forces cancel each other out and also assists with further calculations.

Full Answer >Vector notation is a written method for representing quantities that possess both direction and magnitude, such as acceleration. Vectors are often represented graphically by lines with an arrow pointing in the appropriate direction.
Full Answer >Vector is a quantity that has magnitude and direction. It is represented by an arrow that has the same direction as the quantity and whose length is proportional to the magnitude.
Full Answer >A first-class lever, in which the fulcrum is between the load and the effort, can aid in work by changing the direction of the force and by increasing the efficiency or mechanical advantage of the force applied. The force exerted on a first-class lever has greater mechanical advantage proportional to its distance from the fulcrum.
