Review: Newton's Laws of Motion
Lets go over the three laws and then we will see if you can apply the laws to everyday   situations.

1st law:  An object in motion will stay in motion and an object at rest will stay at rest,
until a force acts on that object.

2nd law:  The force on an object is equal to the product of the mass and acceleration of the object.  (Usually written as the equation 
F = m x a)

3rd law:  For ever force, there is an equal and opposite force.  (For every action, there is  an equal and opposite reaction)
Are you a little confused by Newton and his laws?  Lots of students are! To get some extra review on the ideas behind each law, I suggest that you explore the links LISTED HERE.  These sites have great animations, explainations, and examples of each law.

  When you are finished exploring, come back and take the quiz below.
Can you apply the law?
Read the following situations and decide which of Newton's laws is being demonstated.
1.  The quarterback can throw a dry football with more acceleration than a wet (heavy) football.   

2.  Jim and Bob are riding a go-cart together really fast.  Jim takes a sharp left hand turn and Bob falls out.

3. Fred is riding his mountain bike and runs into a log laying across the trail.  His bike stops but he flips over the handle bars.

4. Sally kicked the bowling ball and it hurt her toe.

5. An easter egg will sit right where you hide it until someone picks it up.

6. You find it easier to push (accelerate) the little red wagon when it is empty compared to when you push the wagon with your sister inside the wagon.

7. Sally and Hayden use 8 pound bowling balls instead of 12 pound bowling balls, because they can roll them faster.

8. When Jacob lset go of his bookbag, gravity pulled the book downward while  the bookbag pulled the Earth upward.

9. After recoverying from cancer, Lance Armstrong was 30 pounds lighter than before he was sick, but he could accelerate his bicycle better than ever.

10.  The horse pulls forward on the wagon with 350 Newtons of force and the wagon pulls backwards on the horse with 350 Newtons of force.
