Term
 Mechanics
Definition
 a branch of the physical sciences that is concerned with the state of rest or motion of bodies that are subjected to the action of forces.
Term
 Statics
Definition
 deals with the equilibrium of bodies, that are either at rest or move at a constant velocity.
Term
 Dynamics
Definition
 deals with the accelerated motion of bodies
Term
 Length
Definition
 used to locate the postion of a point in space and use that to describe the size of the physical system.
Term
 Time
Definition
 conceived as a succession of events.
Term
 Mass
Definition
 a measure of a quantity of matter that is used to compare the action of one body with that of another.
Term
 Force
Definition
 considered as a "push" or "pull" exerted by one body on another.
Term
 Particle
Definition
 has a mass, but a size that can be neglected.
Term
 Rigid body
Definition
 considered as a combination of a large number of particles in which all the particles remain at a fixed distance from one another.
Term
 Concentrated Force
Definition
 represents the effect of a loading which is assumed to act at a point on a body.
Term
 Newton's First Law
Definition
 a particle are rest tends to stay at rest and a particle in motion tends to stay in motion.
Term
 Newton's Secon Law
Definition
 particle acted upon by an unbalanced force F experiences an acceleration a that has the same direction as the forse and a magnitude that is directlty proportional to the force.
Term
 Newton's Third Law
Definition
 The mutual forces of action and reaction between two particles are equal, positive, and collinear.
Term
 Weight
Definition
 the only gravitational force considered in our study of mechanics.
Term
 Newton
Definition
 unit of force that is derived from F = ma
Term
 Slug
Definition
 the unit of mass that is derived from the equation F = ma
Term
 Dimensionally Homogeneous
Definition
 meaning that each term must be expressed in the same units.
Term
 Rigid body, Deformable body, and Fluids
Definition
 What are the three differnt branches of mechanics?
Term
 Because most of the standard equipment that is used is accurate to about .2%
Definition
 Why do most engineers calculations typically only require 3 sig figs?
