Nov. 7th AGENDA: 1 – Bell Ringer 2 – Free Fall Acceleration 3 – Exit Ticket Today’s Goal: Students will be able to explain how free fall acceleration occurs. Homework
CHAMPS for Bell Ringer C – Conversation – No Talking H – Help – RAISE HAND for questions A – Activity – Solve Bell Ringer on binder paper. Homework out on desk M – Materials and Movement – Pen/Pencil, Notebook or Paper P – Participation – Be in assigned seats, work silently S – Success – Get a stamp! I will collect!
Nov. 7th Objective: Students will be able to explain how free fall acceleration occurs. Bell Ringer: 1. What do you think accelerates downwards faster when you drop it: a feather or a hammer? Explain why you think so. 2. Are there any situations in which you would think the opposite happens?

Free Fall When you are in free fall: Is your velocity changing? Are you accelerating?
Free Fall When you are in free fall: Is your velocity changing? Are you accelerating? All objects on earth accelerate downward at -9.81 m/s2
