Friction or Resistance
Sliding friction is shown in hockey when you hit the puck. The puck has friction against the ice (but there isn't much).
Generally, sliding friction is much stronger than rolling friction.
That refers to friction.
Friction opposes motion or, more correctly, relative motion between two bodies in contact.Motion.
Skiing and snowboarding (Skis rubbing against snow slows them down) Skateboarding (Rolling friction, it's a matter of opinion if it supports or opposes them) Swimming (fluid friction makes it harder for them to swim against it) Those are just a few.
