Graphs for an Object in Mechanical Equilibrium
Now, we are going to draw Net Force Versus Time and Velocity Versus Time graphs for a refrigerator which is in mechanical equilibrium. First, we will draw the graphs for a refrigerator which is in static equilibrium (at rest), and then we will draw the graphs for a refrigerator which is in dynamic equilibrium (moving at a constant velocity). Remember: If an object is in mechanical equilibrium, the net force acting on the object is zero. This does not mean that no forces are acting on the object, just that the net force acting on the object is zero.
