Tuesday, April 7th: Using Newton's Second Law

** A note from yesterday.  Several of you commented that it's hard to match pictures with laws.  I agree with you.  Remember that ALL THREE laws will apply to any motion (and any picture of motion).  So there will always be more than one correct answer.  The most important thing will be for your to EXPLAIN YOUR THINKING. **

-------------------------------------------------------------

Newton’s second law tells us that  F = M x A (Force = Mass x Acceleration)

So if we know two of the three numbers, we can figure out the third.  

Let’s practice doing this. 

Example Problem 1: 

A 4kg soccer ball accelerated at 8m/s² when Isaiah kicked it.  What was the force (in Newtons) of Isaiah's kick?

Example Problem 2:

Katie pushed a 30kg box with a force of 10N.  How fast did the box accelerate?

Example Problem 3:

Lucas pulled a wagon with 84 Newtons of force.  The wagon accelerated at 7 meters per second per second.  What was the mass of the wagon?
