Question

Use the position-time graphs for object C and object D to answer the question.

A position-time graph showing Object D with constant velocity (dashed line) and Object C with increasing velocity (curved line).

Does either object have a constant velocity?

Only object D has a constant velocity.
Only object D has a constant velocity.

Neither object has a constant velocity.
Neither object has a constant velocity.

Only object C has a constant velocity.
Only object C has a constant velocity.

Both objects have a constant velocity.

Answer 1

Only object D has a constant velocity.

A straight line on a position–time graph indicates constant velocity (Object D). The curved line for Object C shows changing slope, so its velocity is not constant.
