1 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

2 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!

3 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?

20 Free Fall When you are in free fall: Is your velocity changing? Are you accelerating?

21 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/s 2

22 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground.

23 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground.

24 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground.

25 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = -8.52 m Δt = ? a = -9.81 m/s 2

26 Notes: Kinematic Equations The Four Kinematic Equations: v f = v i + a Δ t Δx = v i Δt + aΔt 2 2 v f 2 = v i 2 + 2a Δx Δx = (v f + v i )Δt 2

27 Notes: Kinematic Equations The Four Kinematic Equations: v f = v i + a Δ t Δx = v i Δt + aΔt 2 2 v f 2 = v i 2 + 2a Δx Δx = (v f + v i )Δt 2

28 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = -8.52 m Δt = ? a = -9.81 m/s 2 Δx = v i Δt + aΔt 2 2

29 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = -8.52 m Δt = ? a = -9.81 m/s 2 Δx = v i Δt + aΔt 2 2

30 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = v i Δt + aΔt 2 2 -8.52 = -9.81 Δt 2 2

31 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = v i Δt + aΔt 2 2 -8.52 = -9.81 Δt 2 2 -8.52 = -4.95 Δt 2

32 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = v i Δt + aΔt 2 2 -8.52 = -9.81 Δt 2 2 -8.52 = -4.95 Δt 2 1.72 = Δt 2

33 Example Theodore drops a pile of roof shingles from the top of a roof located 8.52 meters above the ground. Determine the time required for the shingles to reach the ground. vi = 0 m/s Δx = v i Δt + aΔt 2 2 -8.52 = -9.81 Δt 2 2 -8.52 = -4.95 Δt 2 1.72 = Δt 2 1.32 s = Δt

34 Example Rex Things throws his mother's crystal vase vertically upwards with an initial velocity of 26.2 m/s. Determine the height to which the vase will rise above its initial height.
