Is frictional force really a force since a force is a push or pull? Does frictional force give a push or a pull if its really a force?
Thanks
Thanks
A force can also be applied with no change in momentum, such as the compression force of a vice on a spring.D H said:A force is any thing that results in a change some thing's momentum.

I don't know if all are a push of pull, but I would think so -- friction can either be a push or a pull.ngjingyi said:Is frictional force really a force since a force is a push or pull? Does frictional force give a push or a pull if its really a force?

Friction opposes an applied force. As the applied force can be in either direction or even zero, the force of friction varies too. So is it a force?
Frictional force is a type of contact force that opposes the relative motion or tendency of motion between two objects in contact. It is caused by the interaction between the microscopic bumps and ridges on the surfaces of the objects. This force acts in the opposite direction of the motion, making it harder for the objects to move.
Yes, frictional force is considered a force because it is a push or pull that can cause a change in motion or direction of an object. It can also cause objects to accelerate or decelerate depending on the direction of the force.
Frictional force can either increase or decrease the motion of an object. If the force is in the same direction as the motion, it will slow down the object. If the force is in the opposite direction, it can cause the object to speed up.
No, frictional force cannot be eliminated completely. However, it can be reduced by using lubricants or by using smoother surfaces on the objects in contact. This reduces the amount of interaction between the surfaces and therefore reduces the frictional force.
Some common examples of frictional force include the force between car tires and the road, the force between a pencil and a paper, and the force between a shoe and the ground. Any situation where two objects are in contact and one is moving or trying to move can experience frictional force.
