|
displacement
|
the straight-line distance and direction from one point to another(vector)
|
|
|
distance
|
a scalar quantity that describes the length of a path between two paths
|
|
|
position
|
a vector quantity that describes a specific point relative to a reference point
|
|
|
position-time graph
|
a graph of a subject’s position during a set period of time; time data is plotted on the x-axis(horizontal), and the position data are plotted on the y-axis(vertical).
|
|
|
Scalars
|
Quantities that only have a magnitude (number)
|
|
|
Slope
|
It is the direction of a line on a graph. It can either be horizontal (zero),slanting up(positive), or slanting down(negative).Slope is calculated using the formula rise/run.
|
|
|
uniform motion
|
a motion where the subject is travelling in constant speed in equal time periods; neither speeding up, slowing down nor changing direction.
|
|
|
Vectors
|
They are quantities that have both a magnitude (number) and a direction.
|
|
|
average velocity
|
It is the rate of change in position for a time interval.
|
|
|
Speed
|
The distance an object travels during a given time interval divided by the time interval.
|
|
|
Velocity
|
It is the displacement of an object during a time interval divided by the time interval.
|
|
|
positive slope
|
|
|
|
zero slope
|
|
|
|
negative slope
|
