Rolling Friction
Isn't rolling friction a kind of static friction? CessnaMan1989 (talk) 18:17, 26 January 2021 (UTC)
- No. Static friction occurs between 2 objects when there is no relative motion. It acts to prevent relative motion. In contrast, rolling friction occurs between 2 objects when there is relative motion. The coefficient of rolling friction is much lower than the coefficient of friction for other forms of friction which explains why mankind makes so much use of wheels, ball bearings and roller bearings.
