Work, Power and Energy Key Physics Terms Key Concepts Force : Any influence that tends to accelerate an object; a push or  a pull. Measured in Newtons. Distance:  The quantity that describes the position of an object. Displacement:   The quantity that describes the change in  location of an object  and   includes  its direction of motion. Velocity : The distance an object travels per unit of time  including its direction of motion. Acceleration:  Rate at which an object’s velocity changes with  time; this change  may   in  speed, direction, or both. Vector:  A quantity that  represents   magnitude  (size) and  direction.  It is usually represented with an arrow to indicate the  direction; the arrow may be drawn to scale. Vector Component:  The perpendicular parts into which a vector  Work is done only when a force acts in the direction of  motion of an object. If the force is perpendicular to the direction of motion, then no work  is done. Power is the ratio of work done per unit time.
