Forces and Motion 1. Describe how the change in the position (motion) of an

object is always judged and described in comparison to a

reference point.

2. Explain that motion describes the change in the position of

an object (characterized by a speed and direction) as time

changes.

3. Explain that an unbalanced force acting on an object

changes that object's speed and/or direction.

Nature of Energy 4. Demonstrate that waves transfer energy.

5. Demonstrate that vibrations in materials may produce

waves that spread away from the source in all directions

(e.g., earthquake waves and sound waves).
