On a Velocity-Time Graph:
A horizontal line (slope = 0) above the x-axis means:
constant velocity in the negative direction
constant velocity in the positive direction
acceleration in the negative direction
acceleration in the positive direction
the object has stopped moving
On a V-T Graph:
A horizontal line (slope = 0) below the x-axis means:
constant velocity in the negative direction
constant velocity in the positive direction
acceleration in the negative direction
acceleration in the positive direction
the object has stopped moving
On a V-T Graph:
A horizontal line (slope = 0) ON the x-axis means:
constant velocity to the left
constant velocity to the right
acceleration to the left
acceleration to the right
the object has stopped moving

On a V-T Graph:
A change in direction is shown when:
a line cross the x-axis
a line slopes up then turns down
a line is angled down then angles up
a line is moving towards zero then stops and goes flat
On a V-T Graph:
This shows constant speed and moving to the right:
On a V-T Graph:
This shows speeding up and moving to the right:
On a V-T Graph:
This shows a stationary object or no motion:
On a V-T Graph:
This shows constant speed moving to the left:
Choose all the V-T Graphs below that show acceleration or speeding up:
Choose all the V-T Graphs below that show deceleration or slowing down
Choose all of the V-T Graphs that show a change in direction:
To determine how fast an object is moving on a Velocity-time graph I should...
Look at the vertical axis for that time
Determine the area between the graph & the x axis up to that time
See whether the graph is above or below the x axis at that time
Solve for the slope of the graph at that time
