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
Free Fall

When you are in free fall:

Is your velocity changing?

Are you accelerating?


Free fall1
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


Example
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.

Example2
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.


Example3
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


Notes kinematic equations
Notes: Kinematic Equations

The Four Kinematic Equations:

vf = vi + aΔt

Δx = viΔt + aΔt2

2

vf2 = vi2 + 2aΔx

Δx = (vf + vi)Δt

Notes kinematic equations1
Notes: Kinematic Equations

The Four Kinematic Equations:

vf = vi + aΔt

Δx = viΔt + aΔt2

2

vf2 = vi2 + 2aΔx

Δx = (vf + vi)Δt

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

Example6
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

Example7
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

-8.52 = -9.81Δt2

2

-8.52 = -4.95Δt2


Example8
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


Example9
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.

-8.52 = -4.95Δt2

1.72 = Δt2

1.32 s = Δt
