Interactions between ob'ects cause chan es in The big Idea: motile\" g When objects interact, they can affect each other's motion. Often, this is by pushing or pulling on each otherwhich we call forces. All interactions go both waysif a bat pushes on a baseball, then the baseball pushes on the bat. We often only care about one of the objects, which we call the OBJECT. The other object it interacts with is the AGENT of the force. That means the force we care about is always AGENT on OBJECT. Whether the object will keep doing what it was doing before (such as sitting still or moving with a constant speed) or if it will change its motion (by speeding up, slowing down, or changing direction} depends on if there's a total unbalanced force acting on it from all the other agents it interacts with. For each of the scenarios depicted, decide if the forces acting on each object are balanced or unbalanced. Circle your decision: balanced unbalanced Cart going down a frictionless inclined track. ! balanced unbalanced Ball in free fall balanced unbalanced J' Box attached to parachute at terminal velocity x-hr - E : balanced unbalanced Cart going down an inclined track at constant speed (track has friction). Lab #5: Forces Group Worksheet | Page 1 or 14 1. Balanced vs unbalanced forces These scenarios are shown in videos in the assignment. The important part of the motion for each is listed next to them, which you'll use for reference below. SCENARIO A: car with a mass pulling on it and friction between the cart and the track a ' Constant motion
