Blocks Friction Static Static friction String Tension Tension of string

In summary: If block Q moves to the right, block P will move to the right, and the tension on Q will be the same as the tension on P.

Your notion that the tension would somehow match F2 could only be right if Q were tending to slide left, making T and F2 oppose (and if P and F were not present).

I can finally understand now . Thank you very much !

FAQ: Static friction between 2 blocks and tension of string

What is static friction?

Static friction is a force that prevents two surfaces from sliding against each other when they are in contact and at rest.

How is static friction different from kinetic friction?

Static friction occurs when two surfaces are at rest, while kinetic friction occurs when two surfaces are in motion.

What factors affect the magnitude of static friction?

The magnitude of static friction depends on the nature of the surfaces in contact, the normal force between the surfaces, and any additional external forces acting on the objects.

How is tension in a string related to static friction between two blocks?

The tension in a string is equal to the magnitude of the static friction force between two blocks. This is because the string is what transmits the force between the two blocks, and the force of static friction acts in the opposite direction to the tension in the string.

Can the magnitude of static friction ever be greater than the applied force?

No, the magnitude of static friction can never be greater than the applied force. If the applied force is greater than the maximum static friction force, the objects will start to move and kinetic friction will take over.
