After class, Stevie travels in a straight hallway with a velocity shown in the graph at right, where
Explain what is happening when
Notice that the velocity is negative when
When velocity is negative, Stevie moves back towards his starting position.
Calculate the total distance Stevie traveled.
Total distance is the area under a speed graph. Speed is the absolute value of velocity.
A speed graph is the absolute value of a velocity graph...
Area under a speed graph
Area under a velocity graph
If Stevie only travels in the straight hallway, how far does he end up from his original starting place?
Distance from starting point is known as 'displacement.'
Displacement is the area under a velocity graph.
What was Stevie's acceleration at
Acceleration is slope on a velocity graph.
When was Stevie's acceleration equal to zero?
