#### Slide 2 -Tekstslide

This lesson
•  Discussing the homework
• 1.3 Friction
• Working independently

#### Slide 3 -Tekstslide

Learning goals
• Give examples of friction
• Describe the effect of friction on motion
• Explain how to reduce friction
• Describe how friction can be useful

#### Slide 4 -Tekstslide

balanced forces:
forces that are equal in size
and opposite in direction. Balanced forces do not result in any change in motion.

unbalanced forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
