Definitions
If a position vs. time graph has a horizontal line, this means the object is doing this.
At rest/not moving
On a velocity vs. time graph, time is represented on this axis.
x-axis
What does a horizontal line on an acceleration vs. time graph indicate about an object's motion?
Constant acceleration
The unit for acceleration
m/s/s
The slope of a position vs. time graph gives you this quantity.
Velocity
The slope of a velocity vs. time graph represents this physical quantity.
Acceleration
If the acceleration vs. time graph shows a line at zero (on the time axis), what can you say about the object’s velocity?
Constant Velocity
Definition of acceleration
Change in velocity
The kinematic term with a unit of m/s.
What is velocity?
An object moving at a faster speed will have this type of slope on a position vs. time graph.
A steeper line/slope
A horizontal line above the x-axis on a velocity vs. time graph indicates this type of motion.
Constant Velocity
An acceleration vs. time graph shows a straight horizontal line below the time axis. What kind of acceleration is this called?
Constant Negative Acceleration
An object has constant speed, but it is still accelerating. How?
Changing direction
If an object is at rest, the slope of a position vs. time graph will be this.
Flat/No slope/0
On a velocity vs. time graph, this happens when the line crosses the x-axis
Changes direction
An acceleration vs. time graph shows a flat line below the time axis. Describe in words what the object is doing.
Slowing down in the positive direction, or speeding up in the negative direction.

MTSU
A vector quantity that is the slope of a velocity vs. time graph.
What is acceleration?
When an object turns around, the line on a position vs. time graph does this.
From up (+) to down (-) or vice versa
An object is rolling down a hill, and then it rolls back up another hill in the positive direction. Describe the velocity vs. time graph.
Constant increasing line, constant decreasing line (pyramid shape).
A Velocity vs. time graph shows a line crossing over the time axis from the positive direction to the negative direction. What kind of line will be on an acceleration graph?
