VELOCITY TIME GRAPHS

The Velocity vs. Time Graph Velocity (m/s) Time (s) ∆v ∆t Velocity vs. time

The Slope of the Velocity vs. Time Graph is the Acceleration Positive slopes, positive accelerations negative slopes, negative accelerations v (m/s) t (s) 0

If the graph is above the x axis, it is a positive velocity. If the graph is below the x axis, it is a negative velocity. Velocity Time Graphs

Slowing Down and Speeding Up  An object will only speed up if the velocity and acceleration are in the same direction  An object will only slow down if the velocity and acceleration are in different directions

If the magnitude of the velocity (the number itself, not the sign or direction) is INCREASING; the speed is getting bigger If the magnitude of the velocity (the number itself, not the sign or direction) is DECREASING; the speed is getting smaller Velocity vs Time Graphs
