Question

The motion of a car on a position-time graph is represented with a horizontal line. What does this indicate about the car’s motion? A.It’s not moving. B. It’s moving at a constant speed. C.It’s moving at a constant velocity. D. It’s speeding up.

Answer 1

Answer;

A.It’s not moving.

Explanation;

Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.

The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.

A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.

Answer 2

Actually it DOES mean that it is not moving. That other guy was right and you gave him 2 stars!
