Question

What does a horizontal line on a position-time graph indicate about the object?
(1 point)
O The object remains still.
• The object has a position of zero.
• The object is accelerating.
• The object has a constant, nonzero velocity.

Answer 1

No, a horizontal line indicates a constant position -- that is, zero velocity: so, A: the object remains still.

Answer 2

• The object has a constant, nonzero velocity.

Answer 3

Apologies for the incorrect response. You are correct, a horizontal line on a position-time graph indicates that the object remains still. Therefore, the object has a position of zero. Thank you for pointing that out.
