Representing Motion
Change with time of the position or orientation of a body
Motion
An object must have a constant speed in a constant direction
Constant Velocity
A change in position (rise) over the change in time (run)
Slope
A quantity that has both magnitude and direction
Vector
The center of a coordinate axis, defined as being the coordinate 0 in all axes
Origin
Used to describe the position of an object in space
Coordinate System
A scalar quantity that refers to how fast an object is moving
Speed
A scalar quantity that refers to how much ground an object has covered during its motion
Distance
Defined as the rate at which an object changes its velocity
Acceleration
The universal force of attraction acting between all matter
Gravity
Represents the position, velocity, and acceleration of an object at various clock readings
Motion Map
A vector measurement of the rate and direction of motion
Velocity
The location of an object at any given time
Position
A change in velocity that does not vary over time
Constant Velocity
An object that is falling under the sole influence of gravity
Free Fall
The type of motion in which the object travels in a straight line with uniform speed
Uniform Motion
This shows changes in velocity of a moving object over time
Velocity vs Time Graph
A vector quantity that refers to how far out of place an object is, it is the object's overall change in position
Displacement
The rate at which velocity changes
Average Acceleration
A point or object from which the entity in question is moving
Reference Point
The motion of an object in which the object travels with varied speed and it does not cover the same distance in equal time intervals
Nonuniform Motion
A physical quantity that is completely described by its magnitude
Depicts motion by plotting position relative to the starting point on the y-axis and time on the x-axis
Position vs time graph
The ratio of change in velocity during a given time interval such that the time interval goes to zero
Instantaneous Acceleration
A line that is used to represent the behavior of a set of data to determine if there is a certain pattern
Trend Line
