Learning Objective
I can interpret motion graphs to describe an object's velocity and acceleration.
- 1
On a position versus time graph, a straight line going up represents a positive constant velocity, while a horizontal line means the object has stopped moving.
- 2
To find instantaneous velocity on a position versus time graph, you must find the slope of a tangent line at a certain moment in time.
- 3
On a velocity versus time graph, a horizontal line with a negative y value indicates movement in the negative direction, and a line that slopes up and to the right indicates that an object is speeding up.
