Montgomery County Public Schools 2022 Unit 1: Forces, Motion, and Interactions HS NGSS Physics Tom's Trip: Tom leaves his home, travelling at a constant speed of 2 m/s towards school. After 4 seconds he began accelerating at 2 m/s2, but after two seconds, he realizes that he left his wallet at home, so he negatively accelerates at 4 m/s until he reaches -3 m/s (running back home at 3 m/s). When his velocity reaches -3 m/s, he continues at this constant speed until he reaches his home. Calculating Tom's Motion Variables by Time Interval: noHol guin IanA First Interval: Tom walking at constant speed for four seconds (0
