Friday, April 3rd: Newton's Laws Review

Hi 8th graders!
Remember this guy?  Isaac Newton!

You have something in common with him.  When he was in college his school closed due to the spreading of a highly contagious, dangerous disease.

He used that time to learn on his own and made some really important discoveries.

What awesome things can you do while you are stuck at home??

In any case, before spring break, you finished reading and completing a note-catcher on Newton's Three Laws of Motion.  Our goal for today is to review and practice those laws.

Newton's Laws of Motion:
1.  An object in motion will stay at motion and an object at rest will stay at rest until acted on by an outside force.

2. Force, mass, and acceleration all all related.  Force (measured in Newtons) is equal to the mass of the object (in kilograms) multiplied by the acceleration (in meters per second squared).  That means, if you know two of these three things, you can figure out the third one.   This law is often written as just the equation F = m x a.

3. For every action there is an equal and opposite reaction. 

To review:
You can choose to watch the video below or read This Article About Newton's 3 Laws.  If you are able to do both, that's even better! 

Challenge:  When you watch the video, see if you can figure out what part of the video makes Ms. Dolan cringe. 

Practice:
Review what you know by completing This Review Sheet.  If you can't print it, no problem! You can write your answers on any sheet of paper and send them to me.
