1. Physical Science: Chapter 11, Sec. 1- Motion
_____________of objects is the _______________________________
Frames of Reference
___________________are objects that stay in place. They are not in motion relative to the object in question.
A _______________________is used to describe the motion of an object relative to these reference points.

2. Physical Science: Chapter 11, Motion
The motion of objects is the _____________________________based on a _____________________________.
Did the car
move?
How can
you tell?
In physics, we usually use a “fixed” __________________________________.

3. Physical Science: Chapter 11, Motion
___________________measures how long the path is (total) that an object moves.
___________________measures how far an object traveled from its starting
point (net movement)

4. Physical Science: Chapter 11, Motion

11. Physical Science: Chapter 11, Motion
Average Speed(Velocity)
Remember:
Avg. Speed = ______________
Is _____your “________” speed.
It is an ______________of your speeds for the ____________ distance you moved.
Remember, velocity includes direction in addition to speed.

12. Physical Science: Chapter 11, Motion
________________________ Speed
