Free Fall Lab
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.
