All None

Ignore?
frame of reference
assists one in physics in which one chooses a place (point) a measure it against changes in position.
one-dimensional motion
motion that only takes place in one direction. It is also known as "linear motion".
displacement
A change in position (delta p).
Formula for Displacement
Δx = xf - x i
positive displacement
Used to refer to direction of motion. In this instance positive displacement refers to a direction east. This occurs when you are measuring linear motion (one-dimensional motion).
negative displacement
Used to refer to direction of motion. In this instance negative displacement refers to a direction west. This occurs when you are measuring linear motion (one-dimensional motion).
Velocity
a speed in a particular direction.
slope formula
The formula for the slope of the straight line going through the points (x1, y1) and (x 2, y 2) is given by:
Instantaneous Velocity
How fast an object is moving and direction of motion at each instant in time
