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.

What three conditions are needed for this slip slick motion?

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 is the frictional force needed to start an object at rest into motion.?

static


What do forces opposing motion cause?

Friction


What is the effect of friction on a motion?

Friction will cause the item in motion to heat up. It will also wear the surface away.


Is The force needed to overcome static friction usually less than that needed to overcome kinetic friction.?

True -It's "False"!


True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?

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.


When will a force cause motion?

A force will cause motion, specifically it causes acceleration, whenever it is unbalanced by an opposing force, such as friction.


How does friction cause the motion of an object to change?

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.


When is friction equal to zero?

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.


How is inertia related to friction?

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.


Is it true or false that the motion of an object is affected by friction?

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.


How does friction affect the motion of an object in circular motion?

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.
