When you have a V v T (velocity vs. time) graph, how do you find the displacement that the object traveled?
Read it off the y-axis
Calculate the slope
Find area under the graph
You don't because this graph only shows you the object's velocity
Check all that apply: Velocity is...
the speed at which an object moves in a certain direction
displacement over time
Δd/Δt
the slope of a P v T graph
the slope of a V v T graph
What the first step when you're looking at a graph problem?
Just look at the behavior of the line
Read the y-axis
Which V v T graph matches this P v T graph?
