Question

Describe the difference between the velocity graph made walking at a steady rate and the velocity graph made at an increasing rate.

Answer 1

The difference between the velocity graph made walking at a steady rate means that its the same value in time, that means there's no slope on the graph, so its acceleration is 0

On the other hand, if the velocity is increasing with time, the slope of the graph becomes positive, which means that the acceleration of the particle is positive.
