Question

On a displacement-time graph, what does a linear slope indicate?

A Velocity is changing.
B Velocity is fixed.
C The car is stationary.
D The car is moving forward.

Answer 1

B

Step-by-step explanation:

The slope (change in position over the change in time) represents the speed, or velocity. If the slope is linear, then that means that the velocity is not changing. It is like a constant rate. If you had a curvy line, then the change in position over change in time would also be changing, i.e. the velocity is changing.
