Think of a heavy box lying on the ground with a rope attached for pulling. Until you try to pull the box it doesn't actually resist you. Once you start pulling on the rope, and even if you are unable to move the box, it is as if there is a force pulling against you. This is the force of friction. The friction between the box and the ground sets up this force.
Perhaps you mean friction or inertia.
Friction is independent of speed once an object is moving since faster does not mean more friction.
"Drag" is the name given to the force of air resistance, or friction in general.
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.
Increasing the force of friction means applying a greater opposing force between two surfaces in contact, which makes it harder for one surface to slide or move over the other. This increased force of friction can result in a stronger grip or a greater resistance to motion.
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.
