Force Diagrams (Free Body Diagrams) Example 1 Consider the water bottle below at rest on a table.

Force Diagrams (Free Body Diagrams) Example 2 Consider the water bottle below pulled horizontally across the table at constant velocity.

Force Diagrams (Free Body Diagrams) Example 2a What would change about the force diagram if the bottle was pulled across the table at constant velocity by a rope?

Force Diagrams (Free Body Diagrams) Example 2b What would change about the force diagram if the bottle was pulled from rest across the table by a rope so that its velocity increased?
