Kinematics Glossary Terms Chapter 1

-the study of motion

-a change in an object's location as measured by a particular observer

-the total length of the path travelled by an object in motion

-the line an object moves along from a particular starting point

-a quantity that has only magnitude (size)

-a quantity that has magnitude (size) and direction

-the distance and direction of an object from a reference point

-the change in position of an object

-a vector diagram drawn using a specific scale

-a straight line between two points with a specific direction

-the total distance travelled divided by the total time taken to travel that distance

-the total displacement, or change in position, divided by the total time for that displacement

-a graph describing the motion of an object, with position on the vertical axis and time on the horizontal axis

-a measure of the steepness of a line

m=rise/run

-motion of an object at a constant speed in a straight line

-motion in which the object's speed changes or the object does not travel in a straight line

-how quickly an object's velocity changes over time (rate of change of velocity)

-a graph describing the motion of an object, with velocity on the vertical axis and time on the horizontal axis

-motion in which velocity changes at a constant rate

-the velocity of an object at a specific instant in time

-a graph describing motion of an object, with acceleration on the vertical axis and time on the horizontal axis

-the acceleration that occurs when an object is allowed to fall freely; close to Earth's surface, g has a value of 9.8m/s²

-the acceleration due to gravity of an object in the absence of air resistance

-the velocity of an object when the force due to air resistance equals the force due to gravity on the object
