Question

which quantity or quantities is/are increasing for the object represented by line b? (1 point)
○ velocity and position
○ velocity only
○ velocity and acceleration
○ velocity, position, and acceleration

Explanation:

In physics, if the velocity - time graph is a straight line with a positive slope, velocity is increasing. If the object is moving in the positive direction while velocity is increasing, position is also increasing. Acceleration is the rate of change of velocity. A non - zero positive slope of the velocity - time graph indicates non - zero positive acceleration. So for an object with a line representing its motion having a positive slope on a velocity - time graph, velocity, position, and acceleration are increasing.

Answer:

velocity, position, and acceleration
