Physics - Motion

general terms for Motion

TermDefinition
Frame of Reference point of view of motion with labeled reference points to allow measurements
Position Location or coordinates
Distance how far, a length (ex. 5m)
Displacement The change in position with direction. (final position - initial position) (ex. 10 m East)
Speed how fast (ex. 10 m/s)
Velocity how fast in a given direction (ex. -15 m/s)
Average speed =(total distance / total time)
Instantaneous Speed speed at a specific moment of time
Scalar quantity quantities that are fully described by a magnitude (or numerical value) alone. (ex. Mass, distance, speed)
Vector quantity quantities that are fully described by both a magnitude and a direction. (ex. Weight, Displacement, velocity)
Constant without changing
X-t graph Graph of position and time. Slope is velocity
Motion map Diagram of position and veclocity arrows that is used to show an objects motion
V-t graph Graph of Velocity vs time. Slope is acceleration. (Area under the curve is displacement.)
[m] the unit of meter. used with distance and displacement
[m/s] the unit of meter per second - used with speed and velocity
[m/s^2] the unit of meter per second squared - used with acceleration
