It is never needed to cause motion. Motion continues unless the body is acted upon by a net force (Newtons first law). It MAY be needed to counteract a force opposing motin, like rolling resistence and aerodynamic drag. It MAY be needed to cause acceleration- basically anytime the only form of applying a force involevs interacting with a soid medium, like tyres on a road. It is not needed when accelration can be caused by a reaction, such as a rocket enging.
slow it down, like you
All types of friction act opposite to the direction of motion but static friction is the friction present before motion occurs.
Mainly friction.
resistance to motion is called inertia
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
For slipstick motion to occur, three conditions are needed: a rough surface to cause friction, a force that exceeds the static friction between the surfaces, and the ability for the surfaces to briefly stick during motion before slipping again due to the force applied.

Friction
Friction will cause the item in motion to heat up. It will also wear the surface away.
True -It's "False"!
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
A force will cause motion, specifically it causes acceleration, whenever it is unbalanced by an opposing force, such as friction.
Friction opposes the motion of an object by creating resistance when two surfaces are in contact. This resistance can cause the object to slow down, change direction, or come to a stop altogether, thereby altering its motion.
Friction is equal to zero when objects are in a state of pure rolling motion, such as a ball rolling on a perfectly smooth surface. In such cases, there is no relative motion between the contacting surfaces, so friction is not needed to resist motion.
Inertia is the tendency of an object to resist changes in its motion, while friction is the force that resists motion when two surfaces are in contact. Inertia affects how much friction is needed to overcome the object's resistance to motion. Higher inertia means more friction is required to change the object's motion.
True, friction is a force that opposes the motion of an object when it is in contact with another surface. Friction can cause the object to slow down or stop moving.
Friction can slow down the motion of an object in circular motion by creating resistance against its movement. This resistance can cause the object to lose speed and eventually come to a stop.
