wiki Word:rolling  friction

 

 

 

Definition:the resistance that occurs when a ball or      tire rolls across a surface.[1]                                          

                                                                                                                                                            

For example a car rolling(moving) on the ground is   experiencing rolling friction because the car is           moving against the asphault.                                   

                                                                                                                                                              

                                                                                          

                                                                                          

                                                                                          

                                                                                                                                                                      

 

 

In our air rocket car lab we had to consider rolling friction in the equasion to get our car to move. If the wheels were not round enough there would be to much friction and the car would not move.
