Position
The location of an object at any given time.
Position vs Time Graph
Position x of a particle is plotted on the y-axis and the time T on the x-axis.
Speed
How fast an object is moving.
Nonuniform Motion
The type of motion in which the object travels with a varied speed.
Gravity
The universal force of attraction acting between all matter.
Distance
Total path covered by the object in motion, irrespective of the direction of the path.
Slope
The ratio of the change in the y-axis to the change in x-axis.
Velocity
The rate at which an object changes its position.
Acceleration
Vector quantity that is defined as the rate at which an object changes its velocity.
Free Fall
State of an object that moves freely in any manner in the presence of gravity.
Displacement
The change in position of an object.
Motion Map
Map that represents the position, velocity, and acceleration of an object at various spaces.
Constant Velocity
An object is moving equal distances at equal intervals of time and does not change its direction.
Constant Acceleration
Change in velocity that does not vary over time.

Coordinate System
Describe the position of an object in space.
Vector
An object that has both a magnitude and a direction.
Velocity vs Time Graph
The slope of a velocity graph represents the acceleration of the object.
Average Acceleration
The rate of change of velocity, or the change in velocity per unit time.

Origin
Center of a coordinate axis, 0 in each axis.
Scalar
Quantities that are described by a numerical value.
Uniform Motion
Motion of an object in which the object travels in a straight line, and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
Instantaneous Acceleration
The ratio of change in velocity during a given time interval.
