bject will keep doing what it was doing before (such as siJng s4ll or moving with a constant speed) or if it will change its mo4on (by speeding up, slowing down, or changing direc4on) depends on if there's a total unbalanced force ac4ng on it from all the other agents it interacts with. For each of the scenarios depicted, decide if the forces ac4ng on each object are balanced or unbalanced. Circle your decision: The big idea: Interactions between objects cause changes in motion balanced unbalanced balanced unbalanced balanced unbalanced balanced unbalanced Cart going down a frictionless inclined track.
