Free-Fall Acceleration Laboratory Help Sheet
* Design an experiment :-UNIT 2 Lesson 3 page 1

* Hypotheses UNIT 2 Lesson 3 page 2
How do you think the free fall acceleration will be different on Earth, Moon and Mars and why?

* Data collection and organization. UNIT 2 Lesson 3 page 3,4

EARTH
Time (s)| 0| 0.2| 0.4| 0.6| 0.8| 1.0|
Distance (m)| 0| x| | | | |
Average Velocity m/s| 0| A| B| | | |
Acceleration m/s/s| 0| | C| | | |

Example to calculate average velocity A
A= x - 0 (change in distance)
0.2 - 0 (change in time)
Repeat for all other velocities

Example to calculate acceleration C
C = Velocity B - Velocity A (change in velocity)
0.4 - 0.2 (change in time) Repeat for other accelerations

MOON
Time (s)| 0| 0.4| 0.8| 1.2| 1.6| 2.0|
Distance (m)| 0| | | | | |
Average Velocity m/s| 0| | | | | |
Acceleration m/s/s| | | | | | |

MARS
Time (s)| 0| 0.3| 0.6| 0.9| 1.2| 1.5|
Distance (m)| 0| | | | | |
Average Velocity m/s| 0| | | | | |
Acceleration m/s/s| | | | | | |

* Constructing Graphs UNIT 2 Lesson 3 page 4

You will create 9 graphs. 3 graphs for each environment. You may use Microsoft Excel to create the graphs or regular graph paper (no lined or plain paper). Use a pencil for drawing graphs and a ruler. Units should be shown on both X and Y axis. Graphs should have a title.
