Final answer:
To automatically change an object's draggability, you can manipulate the applied force and friction in a physics simulation software. By observing the resulting changes in friction, one can see how object motion is affected.
Step-by-step explanation:
To automatically change the draggability of an object, you can use a physics simulation platform on a computer. First, you would select the Friction tab within the software. Here, you can choose different objects that a simulated person may push. Applying a force is done by sliding the applied force button to the right (to apply force to the right) or to the left (to apply force to the left). The force remains being applied as long as the button is held down. Observe how the arrow representing friction alters in magnitude and direction in response to the amount of force applied. By adjusting the friction force, you can see how changes in friction affect the object's motion. Increasing friction will generally slow down an object, while decreasing it allows the object to move more easily, sometimes even when no additional force is applied.
