Question

Which statements accurately describe the motion map? Check all that apply.

The objects are moving in the same direction.
The objects are moving in opposite directions.
Object A has a greater velocity than object B.
Object B has a greater velocity than object A.
Objects A and B have the same velocity.

Answer 1

I don’t have the motion map image, so I can’t pick which statements are correct for your specific diagram. If you can upload the motion map or describe the arrows/dot spacing I’ll answer directly.

How to determine the correct statements from a motion map:
- Direction: look at the arrowheads on each object’s track. If both point the same way, the objects move in the same direction. If they point opposite ways, they move in opposite directions.
- Speed (magnitude of velocity): compare the spacing between successive position marks (dots) for A and B. Larger spacing between consecutive marks (for the same time interval) means a larger speed. Equal spacing means equal speed. If spacing changes, the object is accelerating (so instantaneous velocities vary).

Examples:
- If both arrowheads point right and A’s dots are farther apart than B’s: “The objects are moving in the same direction” and “Object A has a greater velocity than object B.”
- If arrowheads point opposite ways and both have equal spacing: “The objects are moving in opposite directions” and “Objects A and B have the same velocity.”
- If both arrowheads point right and both have equal spacing: “The objects are moving in the same direction” and “Objects A and B have the same velocity.”

Send the map or describe arrows and dot spacing and I’ll mark which statements apply.
