Aiden read about elastic and inelastic collisions and analyzed the diagrams of each. He completed the 3-Dimensional Thinking asking what effect would slowing down a collision have on force between two objects. He read the passage "A Closer Look: SAFER Barriers" which explains how racetrack barrier technology has improved to absorb the shock from a crash and slow down the acceleration which slows down the force, saving lives. He completed the Force Pairs lesson review and we went over the answers.
