1. EGG DROP ACTIVITY PHYSICS: USING GRAVITY

2. FLASH BACK 10/15/12 1. USE YOUR NOTES TO CALCULATE THE WEIGHT FORCE THAT A 75 kg OBJECT WOULD FALL WITH: A. 75 N B. 750 N C. 10 m/s 2 2. CALCULATE THE WEIGHT FORCE THAT A 100 kg OBJECT WOULD FALL WITH: A. 1,000 N B. 100 N C. 10 m/s 2 3. CALCULATE THE ACCELERATION THAT A 1,000 kg OBJECT WOULD FALL WITH: A. 10 m/s 2 B. 30 m/s 2 C. 20 m/s 2

3. Your Mission Your mission is to safely return an egg to Earth after being dropped from the ceiling, using only the limited resources on your sheet.

4. Assignment Rules 1. Only the materials provided are allowed for use. 2. Only white glue or hot glue are allowed. 3. No materials can be directly glued to the eggs. 4. Not all materials have to be used.

5. Step 1 STEP 1: DESIGN AN EGG DROP APPARATUS What is your GOAL? -What is your GOAL? -What will your Egg Drop apparatus look like, and what materials will you use and where will you use them?

6. FLASH BACK 10/16/12 1. USE YOUR NOTES to calculate the acceleration of a 50 kg object being dropped off of a cliff: A. 10 m/s 2 B. 30 m/s 2 C. 20 m/s 2 2. USE YOUR NOTES to calculate the acceleration of a 60 kg object being dropped off of a cliff: A. 10 m/s 2 B. 30 m/s 2 C. 20 m/s 2 3. Choose the letter of the best definition for INERTIA: A. An object slowing down due to friction. B. An object’s tendency to resist change in its motion. C. An object’s acceleration.

7. FLASH BACK 10/17/12 1. Without using calculations, what is the rate of acceleration that ALL objects will fall to the earth with: A. 10 m/s 2 B. 30 m/s 2 C. 20 m/s 2 2. USE YOUR NOTES to calculate the acceleration of a 60 kg object being thrown with a force of 120N: A. 1 m/s 2 B. 2 m/s 2 C. 3 m/s 2 3. Choose the letter of the best definition for INERTIA: A. An object slowing down due to friction. B. An object’s tendency to resist change in its motion. C. An object’s acceleration.

8. FLASH BACK 10/23/12 COMPLETE THE BLANKS BELOW 1. An object in motion tends to stay in motion because of its: 2. A feather and a rock dropped at the same time would land at the same time under which circumstance: A.) astronaut on the moon B.) Astronaunt from a space shuttle 3. Acceleration of an object ________________when mass is added? a.) increases b.) decreases

9. Additional Problems: F = M x A; A=F÷M 1.) Calculate the acceleration of a 30 kg rock being thrown with a force of 15N: 2.) Calculate the force of a 30 kg rock being thrown with an acceleration of 20 m/s/s:
