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.
In a D vs T graph, when the line is horizontal, it means the car did not change any position over the period of time. so if no position is changes, the car is not moving.
