Lecture on Acceleration or Equilibrium

When all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium. This extends from Newton’s first law of motion. But having an acceleration of 0 m/s/s does not mean the object is at rest. General purpose of this lecture is to present on Acceleration or Equilibrium. It is a tutorial based lecture. Here briefly etermine whether the following diagrams (in lecture) illustrate acceleration or equilibrium. Number your paper from 1 to 5 and answer A if you think it is showing acceleration or E if you think it is showing equilibrium.
