Physics Unit: Newton's Laws of Motion

Newton's First Law: Inertia 

Assessment:

Type up with a table and graph of your results.  Send to the taroonawork gmail account.

QUESTIONS:

         1.How would you describe, in your own words, Newton’s First Law of Motion?

2. What did you predict would happen in the experiment? What actually happened? Use the actual numerical results to support your statements. 

3.How does this experiment relate to Newton’s First Law? What forces were at play on the cart and on the Crash Test Dummy?

4.List three circumstances where you have seen or felt Newton’s First Law take place.  

5. Was this a fair test? Write a list about what might have influenced the accuracy of your results.  How could you improve this experiment for next time?

EXTENSION INVESTIGATION:

Use the PHeT cannon simulator (see below) and draw up a table in your book to explore this question > Do heavier things go further and faster? 

How to use the cannon simulator 
https://phet.colorado.edu/sims/projectile-motion/projectile-motion_en.html
1. Select "user choice" projectile
2. Turn on air resistance
3. Put angle on 33 degrees
4. Now experiment with different masses (try between 10kg - 200kg)
5. Use the information at the top of page to add to your table.
