1) Zoe the stunt woman jumped off the top of a building (there was a rescue pad at her landing). Her friend Mike used a special radar
device to measure her velocity each second. His data is recorded below. Calculate Zoe’s acceleration each second and fill in the 4th

3) Create your very own, acceleration poster! Make your poster creative and fun.
Rules: ● nobody can get hurt ● scale: 1 cm = 10 m ●building 330 meters tall ● mark & label position every 1 second
To Create your poster:
You will need to complete the following on a piece of paper or poster board that is at least 22 inches long and 15 inches tall.
Look at the next page for an example.
Divide your poster into three columns
Labe the first column Earth the second column Mercury and the third column Jupiter.
In the Earth column construct your building and make it 33 cm tall.
Show where Zoe the stunt woman is every second on her freefall descent.
Follow all the directions on the oand answer the questions on page 2 above. You will end up creating similar diagrams for Mercury and Jupiter.

Answer Key for Remainder of Questions:
(Use only to check your work and make corrections)
4) Describe Zoe’s acceleration due to gravity in words (at least two complete sentences).
Zoe’s acceleration due to gravity is constant. As she falls she accelerates at a constant 10 m/s/sec meaning that for
every second she falls she gains another 10 m/s of speed.
12
5) Is acceleration due to gravity constant (explain)?
Because the force of gravity on Earth does not change the
acceleration due to gravity on Earth is a constant. It is
about 10 m/s/sec.
6) Study the numbers in column 6 and column 7 of your data table.
Describe the patterns you see.
Write your observations here. We will discuss these.
7) What is the Law of Falling Bodies?
8) Create a new data table. Complete the table for an object falling
330 meters on the planet Mercury (g Mercury = 2.0 m/s/s).
In the middle section of your poster draw the locations each
second of a person falling 330 meters on the planet Mercury.
See the previous pages for a blank table to use. The
acceleration has been filled in for you and you need to do the
rest.
9) Describe in at least two sentences how falling on Mercury
differs from falling on Earth:
The acceleration is a lot less. Therefore it takes longer to
reach a given speed. It would be like falling in slow motion.
10) Make a data table and complete the far right section of your
poster for the planet Jupiter (g Jupiter = 24.0 m/s/s). Describe
how falling on Jupiter compares to falling on Mercury and Earth.
Falling Bodies
A. Who discovered the Law of Falling Bodies? Galileo
B. The Law of Falling Bodies is … All bodies (objects) fall
with the same constant acceleration in the absence of air
resistance or other forms of friction. This condition is
found in a vacuum (where there is no air) such as in
space.
C. What did the astronaut demonstrate on the moon?
Draw a sketch. That a hammer and feather will fall at
the exact same rate in the absence of air. That is he
demonstrated Galileo’s law of falling bodies.
D. Why do things fall that way on the moon?
Because there is no atmosphere (air).
E. Regarding the penny and feather in the bell jar.
i. How did they fall before the air was sucked out?
Penny fell faster than feather.
ii. How did they fall after the air was sucked out?
They fell at the exact same rate.
iii. Explain
There was no air to slow down the feather.
F. How does mass affect acceleration due to gravity?
It has NO effect on an object’s acceleration.
G. What is the actual value of acceleration due to gravity
here on Earth? 9.8 m/s/s
You accelerate much faster. It only takes a few seconds to
13
fall the whole 330 meters..
