# SLS Sci10 Motion NT

TermDefinition
Average velocity the rate of change in position for a time interval
Displacement the straight-line distance and direction from one point to another
Distance (d) a scalar quantity that describes the length of a path between two points or locations
Position (d with an arrow) a vector quantity that describes a specific point relative to a reference point
Position-time graph a graph of an object’s position during corresponding time intervals; time data are plotted on the horizontal axis (x-axis), and position data are plotted on the vertical axis (y-axis)
Scalars quantities that have only a magnitude (do not include direction)
Slope the direction of a line on a graph, either horizontal (zero), slanting up (positive), or slanting down (negative). Slope is calculated by determining the ratio of rise/run.
Speed (v) the distance an object travels during a given time interval divided by the time interval
Uniform motion travelling in equal displacements in equal time intervals; neither speeding up, slowing down, nor changing direction
Vectors quantities that have both a magnitude and a direction
Velocity (v) the displacement of an object during a time interval divided by the time interval
