Velocity–Time Graph Explorer – AP Physics 1

1. If a v-t graph is a straight line with negative slope, what is the object doing?

Moving backward at constant speed Decelerating (or reversing direction) Moving forward with increasing speed At rest

2. What physical quantity equals the area under a v-t graph?

Speed Acceleration Displacement Force

3. An object has v₀ = 12 m/s and a = −3 m/s². When does it momentarily stop?

t = 3 s t = 4 s t = 6 s t = 12 s
