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 moveExample: Mrs. Szymanski asked Adam to pick up his
pencil, but it remained stationary on his desk.
Motion
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!
Reference Point
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!
Reference Point
Force = a push or pull1. 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 object1. 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?
Force
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
Fun Facts
Extreme athlete
Jumped from a helium-filled balloon at approximately 129,000 feet above the ground
Part of atmosphere involved: troposphere and stratosphere
Felix Baumgartner
Getting Ready for the Jump
The Real Deal
The Force is Always With You
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)?
