velocity and position

Answer 1

Answer: velocity and position.

Reason: On a velocity–time graph, the slope gives acceleration. Line B has a positive slope, so velocity is increasing (acceleration is positive). But the acceleration is constant (the slope is constant), not increasing, so acceleration is not “increasing.” Because the velocity is positive and increasing, the object's position is also increasing.
