accelerated motion: motion of an object that is either increasing or decreasing in speed or changing direction
acceleration: a measure of the rate of change of velocity in relation to time
acceleration-time graph: a graph showing the acceleration of an object at varying times, where time is the independent variable and acceleration is the dependent variable
area: a quantity specifying the size of a region
area relationships: used to find velocity from an acceleration-time graph or displacement from
a velocity-time graph
Cartesian method: a system for measuring directions using the x-axis and y-axis
direction: the course that an object follows
displacement: a change in position including both magnitude and direction
distance: the length of the path taken to move from one place to another
instantaneous velocity: the velocity of a object at an instant of time; the slope of the tangent line to the position-time graph for the selected time
kinematics: the study of motion without concern for forces, masses, or energy
navigator method: a system for measuring directions using compass bearings
non-uniform motion: motion that is not at a constant speed in a straight line
one-dimensional motion: motion in a straight line
position: the straight-line distance and direction of an object from the origin
position-time graph: a graph showing the position of an object at varying times, where time is the independent variable and position is the dependent variable
scalar quantity: a measurement that has only magnitude
sign convention: a system for designating directions along a straight line; one direction is positive and the other is negative
slope: a measure of the steepness of a curve
speed: a measure of the distance travelled per unit of time
uniform motion: motion at constant speed in a straight line
vector quantity: a measurement that has a magnitude and a direction
velocity: a measure of the rate of change of position in relation to time
velocity-time graph: a graph showing the velocity of an object at varying times, where time is the independent variable and velocity is the dependent variable
