2.  Motion: change in an object’s position over time. ◦ This can look different depending on where you are  Reference point: a stationary object against which motion is measured ◦ Easier way to say it: find an object that doesn’t move. Then compare your moving object to the one not moving. Stationary = doesn’t move Example: Mrs. Szymanski asked Adam to pick up his pencil, but it remained stationary on his desk.

3. Look at my object on the table. 1. Is it moving? 2. How do you know? 3. What proof do you have? Look behind you and don’t peek until I say to look!

4.  Look at the object now. 1. Did it move? 2. How do you know? 3. What proof do you have? Use the words “motion” and “reference point” in your answer. Be ready to share!

5.  Force = a push or pull 1.What is a force you know about? 2.Is the force you know about a push or a pull?  Mass = the amount of matter in an object 1.The ______ mass an object has, the ______ force is takes to move that object. Which would not easily be moved by you: A Thomas the Train toy or a real life train?

6.  747 Jets usually fly between 30,000 and 40,000 feet from the ground  Skydivers typically jump no higher than 13,000 feet  Highest clouds can form up to 60,000 feet in tropical regions

7.  Extreme athlete  Jumped from a helium-filled balloon at approximately 129,000 feet above the ground  Part of atmosphere involved: troposphere and stratosphere

8.  Getting Ready for the Jump Getting Ready for the Jump  The Real Deal The Real Deal

9. 1. What force caused Felix to come back to Earth? 2. Was he push or pulled back to Earth? 3. Why couldn’t he open his parachute as soon as he came out? 4. What causes his parachute to arc like that (create that curved look that we know parachutes make)?
