  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?

  4. 4 MINUTES REMAINING…

  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/s2

  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 dropsa 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 dropsa 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/s2

  26. Notes: Kinematic Equations The Four Kinematic Equations: vf = vi + aΔt Δx = viΔt + aΔt2 2 vf2 = vi2 + 2aΔx Δx = (vf + vi)Δt 2

  27. Notes: Kinematic Equations The Four Kinematic Equations: vf = vi + aΔt Δx = viΔt + aΔt2 2 vf2 = vi2 + 2aΔx Δx = (vf + vi)Δt 2

  28. Example Theodore dropsa 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/s2 Δx= viΔt + aΔt2 2

  29. Example Theodore dropsa 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/s2 Δx= viΔt + aΔt2 2

  30. Example Theodore dropsa 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 = viΔt + aΔt2 2 -8.52 = -9.81Δt2 2

  31. Example Theodore dropsa 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 = viΔt + aΔt2 2 -8.52 = -9.81Δt2 2 -8.52 = -4.95Δt2

  32. Example Theodore dropsa 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 = viΔt + aΔt2 2 -8.52 = -9.81Δt2 2 -8.52 = -4.95Δt2 1.72 = Δt2

  33. Example Theodore dropsa 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 = viΔt + aΔt2 2 -8.52 = -9.81Δt2 2 -8.52 = -4.95Δt2 1.72 = Δt2 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.
