Graph vs Graph vs Map

Position vs. Time, Velocity vs. Time, and Motion Maps

1) Position vs. Time

• y-int = starting point
• x-axis = reference point
• flat lines = the object is stopped at one position
• positive slope = object traveling away from reference point
• negative slope = object traveling toward reference point
• slope = velocity (displacement/time)

2) Velocity vs. Time

• flat horizontal lines = constant velocity
• x-axis = object is stopped
• above the x-axis = positive velocity (moving away from reference point)
• under the x-axis = negative velocity (moving toward reference point)
• vertical lines = change in velocity

3) Motion Map

• dot = second 
• arrow = distance traveled in a second
• short arrows = low velocity
• long arrows = high velocity
• dot (no arrow) = no movement
• right arrows = positive movement away from reference point
• left arrows = negative movement toward reference point
