In (the partial) solution, why does it consider the Tension,T, for finding the friction force between m1 and the surface? The tension is only affecting m1 in the horizontal direction. From where, the vertical component is apperaing?
Careful. The tension pulls on the pulley--which is attached to m1--in two directions.senior said:The tension is only affecting m1 in the horizontal direction.
Friction force is the resistance force that occurs when two surfaces come into contact with each other and slide or try to slide against each other.
Friction force can either help or hinder motion depending on the situation. It can help to slow down or stop an object in motion, but it can also provide the necessary force to start motion.
The amount of friction force depends on the nature of the two surfaces in contact, the force pressing the surfaces together, and the roughness or smoothness of the surfaces.
Tension is a pulling force that occurs when an object is stretched or pulled by a force acting in the opposite direction.
Tension can cause objects to stretch or deform, as well as provide the necessary force to keep an object in place or maintain its shape.
