Rolling friction is ____________ sliding and static friction.

$\huge\bold{{\pink{A}}{\blue{N}}{\green{S}}{\red{W}}{\purple{E}}{\orange{R}}{\green{❥}}}$

Rolling friction is less than sliding and static friction.

$\bold{\boxed {\pink{Static  Friction  ➳}}}$

Static friction is the frictional force that exists between two bodies so long as they are relatively at rest, even though an external force is acting upon them. It is the opposing force that comes into play when one body tends to move over the surface of another but actual movement has not started. Static friction must be overcome before an object can be set in motion.

$\bold{\boxed {\pink{Sliding  Friction  ➳}}}$

The force of friction acting between two bodies when they slide on one another with a uniform speed is called sliding friction. When an object starts sliding, the contact points on its surface do not get enough time to lock into the contact points on the floor. So sliding friction is slightly smaller than static friction.

$\bold{\boxed {\pink{Rolling  Friction  ➳}}}$

The force of friction that exists between two surfaces when a body rolls over the other body is called rolling friction. Rolling reduces friction. That is why it is easy to move a heavy box when it is fitted with wheels. We will need to apply a lot of force, if it is without wheels.
