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.
What will the motion of the cart be like when there is no force at all there is no force friction in this model?
If there is no external force acting on the cart and no friction present, the cart will continue to move in a straight line at a constant velocity due to its inertia. It will keep moving unless acted upon by an external force.
Which is the self adjusting force?
Self-adjusting force is a force that changes in response to external conditions to maintain equilibrium or balance. It enables systems to adapt and regulate their own behavior without external intervention.
What are the two external forces?
The two external forces are friction and air resistance. Friction is the force opposing motion when two surfaces are in contact, while air resistance is the force acting in the opposite direction to an object's motion as it moves through the air.
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.
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.
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.
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 will the motion of the cart be like when there is no force at all there is no force friction in this model?
If there is no external force acting on the cart and no friction present, the cart will continue to move in a straight line at a constant velocity due to its inertia. It will keep moving unless acted upon by an external force.
What is the key external force that allows a man to push a shopping cart?
Friction.

What are the two external forces?
The two external forces are friction and air resistance. Friction is the force opposing motion when two surfaces are in contact, while air resistance is the force acting in the opposite direction to an object's motion as it moves through the air.
What is static frictions?
In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object. ... The frictional force itself is directed oppositely to the motion of 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 cause object to move?
Objects move when an external force is applied to them. This force can come in various forms, such as push, pull, gravity, friction, or tension. The object's movement is determined by the direction and magnitude of the force acting upon it.
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.
