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.
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
limiting force is basically just friction
Friction.
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
To find the friction coefficient in a given system, you can use the formula: Friction coefficient Force of friction / Normal force. The force of friction is the force resisting the motion of an object, and the normal force is the force exerted perpendicular to the surface the object is on. By dividing the force of friction by the normal force, you can calculate the friction coefficient.
Statical friction
The friction vs normal force graph shows that there is a direct relationship between friction and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is dependent on the normal force acting on an object.
The force acting on an object increases the friction between the object and the surface it is on. As the force increases, the friction force also increases proportionally until it reaches a maximum value, called the limiting friction. This relationship is described by the equation: friction force = coefficient of friction * normal force.
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
The reaction force to the friction acting on the car is the friction force acting on the road. It acts on the car in the opposite direction to the friction force acting on the car.
The Force of friction is equal to the coefficient of friction times the normal force. Since normal force is equal to mass times the acceleration of gravity (9.8 m/s2), the force of friction is directly proportional to the mass.
Sliding friction requires more force to overcome its friction.
Sliding friction requires more force to overcome its friction.
The force that acts on objects that are not moving is static friction. Static friction prevents the object from moving when a force is applied to it, until the force overcomes the static friction and causes motion.
