Force
The force that opposes motion when moving objects over a surface is called friction
Friction.
Friction.
Friction is a force that opposes the motion of any object moving on it.
Lift is the upward force that opposes the force of gravity.
Friction is a force that opposes all movement to slow down a moving object.

Friction is a force that opposes the motion of any object moving on it.
A centripetal force is a force that pulls something, that is moving in a circle, towards the center - in other words, keeping it in circular motion.
Lift is the upward force that opposes the force of gravity.
Friction forces.
No force is required to keep something moving. According to Newton's Second Law, you need a force to speed something up, or to slow something down - not to keep it moving.
If you're talking about something in say a tank of water, the buoyant force points up and opposes the downward force of gravity......
