1. Laws of Motion NGSS Energy Unit 3

2. Newton’s First Law of Motion  An object will remain at rest or move in a straight line with constant speed unless it is acted upon by a force.

3. Newton’s First Law of Motion at the Space Station

4. STOP! … Quick demo!  Place the index card on top of the beaker.  Place a penny on the top of the index card.  As quick as you can, pull the index card off the top of the beaker.  What happens to the penny?  On your foldable… draw a picture demonstrating what occurred to the penny using Newton’s 1 st Law of Motion.  Place the index card on top of the beaker.  Place a penny on the top of the index card.  As quick as you can, pull the index card off the top of the beaker.  What happens to the penny?  On your foldable… draw a picture demonstrating what occurred to the penny using Newton’s 1 st Law of Motion.

5. Newton’s Second Law of Motion  An object acted on by an unbalanced force will accelerate in the direction of the force with an acceleration equal to the force divided by the objects mass. a = F/m  An object acted on by an unbalanced force will accelerate in the direction of the force with an acceleration equal to the force divided by the objects mass. a = F/m

6. Newton’s Second Law of Motion at the Space Station

7. STOP!! … Quick demo!  Place a penny and a piece of popcorn at the end of your table.  For the first trial, blow the popcorn across the table with only ONE breath.  For the second trial, blow the penny across the table with only ONE breath.  What object traveled the farthest? Why?  On your foldable, DRAW a picture demonstrating what occurred to the penny and popcorn using Newton’s 2 nd law of motion.  Place a penny and a piece of popcorn at the end of your table.  For the first trial, blow the popcorn across the table with only ONE breath.  For the second trial, blow the penny across the table with only ONE breath.  What object traveled the farthest?
