It's All About the Friction!

This rock stays in place due to static friction forces!

This polar bear slides over the ice due to kinetic (sliding)friction forces

Big Idea! - Forces have magnitude and direction

I can....

• Experiment with kinetic friction and drag by using an object that has limited friction

Vocabulary:  drag, kinetic friction, static friction, acceleration

Question 1:  Study the pictures below - which ones show examples of static friction and which ones show examples of kinetic friction    

 Example 1 

                                                                   

Example 2

 

                       Example 3

                                Example 4

Example 5
