Question

The graphs on this page represent the motion of objects along a line that is the positive position axis. notice that the motion of objects is represented by position, velocity, or acceleration graphs. answer the following questions. you may use a graph more than or not at all, and there may be more correct choices than blanks if none of the graph is correct, answer . pick one graph that give enough information to indicate that the velocity is always negative. pick three graphs that represent the motion of an object whose velocity is constant (not changing). pick one graph that definitely indicates an object has reversed direction. pick one graph that might possibly be that of an object standing still. graphs that represent the motion of objects whose acceleration is changing. a velocity graph and an acceleration graph that could describe the motion of the same object during the time shown. velocity graph. acceleration graph.

Explanation / Answer

12) a       velocity is slope of pos. time graph hence slope is negative for a

13) a        14) f       15)i

17)i

18)b     19)e    20)g   

21)c    22)h   constant decelaration or    21)f           22)i     zero acceleration
