Distance and Displacement Flashcards
Study of motion
Mechanics
Description of motion
Kinematics
Explaining motion
Dynamics
treating objects as particles
Idealization
a vector that points from a common reference point to the actual location of the object in space
Position
a vector that points from an object’s initial position to its final position
Displacement
Its magnitude is the shortest directed distance between the two positions
Displacement
a scalar quantity that states when and how long the motion occurs
Time
It is used in referring to a specific time an object is at a particular point.
Time Interval
refers to the time rate change of an object’s position between its initial and final positions
Average Velocity
It represents the time progression of an object’s position.
Position Time Graph
the slope of the line connecting x1 and x2
Average velocity
velocity at a specific instant in time
Instantaneous Velocity
It is the slope of the tangent line in the x-t graph
Instantaneous Velocity
the slope of the line joining v1 and v2
Average acceleration
