Is friction considered an external force?
Yes, friction is considered an external force because it acts on an object from outside of it, affecting its motion or resistance to motion.
Is friction an external force?
Yes, friction is an external force that opposes the relative motion or tendency of motion between two surfaces in contact. It is caused by the interaction of molecules at the surface of the two objects.
How does a mass-spring system with recoil and friction behave under varying external forces?
A mass-spring system with recoil and friction will exhibit different behaviors when subjected to varying external forces. The recoil force will cause the system to oscillate back and forth, while friction will gradually dampen the oscillations. The system's response to external forces will depend on the magnitude and frequency of the forces applied.
Does a stationary object contain friction?
A stationary object does not experience friction if all external forces acting on it are balanced. Friction only comes into play when there is relative motion or an attempt to move the object.
What friction is greater than sliding friction?
Static friction is greater than sliding friction. Static friction occurs when an object is at rest and an external force is being applied to move it, requiring a greater force to overcome the initial resistance compared to when the object is already in motion and experiencing sliding friction.

What will happen to the value of friction force when external force acting on the body with mass m is increased from zero to F max such that there is impending motion at F max?
The value of the friction force will increase to match and oppose the external force up to a maximum value known as the static friction force. Once the external force exceeds the maximum static friction force, the object will begin to move, and the friction force will decrease to the kinetic friction force, which is generally lower than the maximum static friction force.
How does friction affect the law of inertia?
Friction has no effect whatsoever on the law. But if friction is present, then the law can't be demonstrated, because the moving object always has an external force acting on it.
What is the key external force that allows a man to push a shopping cart?
Friction.
What are the consequences of friction?
Friction requires that forces be greater to move an object, but friction also makes it possible for an object to stop moving without an external applied force. Remember, friction ALWAYS opposes motion.
Why can friction make observing Newtons first law of motion difficult?
Newton's first law of motion categorizes any force affecting the motion as an external force. Friction being an external force, negates its presence as an integral force of a motion. Hence friction cannot be used to observe first law of motion.

What are some examples external forces?

Why is friction a force?
Friction is considered a force because it acts on an item and causes changes, which is what a force is. Nothing would happen if the item was in an area where friction was not possible or if friction was where an object was not since they need each other to exert external effort.
What friction is greater than sliding friction?
Static friction is greater than sliding friction. Static friction occurs when an object is at rest and an external force is being applied to move it, requiring a greater force to overcome the initial resistance compared to when the object is already in motion and experiencing sliding friction.
