    Friction
In summary, there are two boxes, m1 and m2, with weights 12kg and 23kg respectively, connected by a rope and with a force of 50N pulling on m2. The tension of the string and the acceleration can be calculated, but there is also the factor of friction to consider, with a coefficient of kinetic friction of .1 between each block and the surface. To account for this, one can draw freebody diagrams for both blocks and consider the forces acting on them.

so you have two boxes m1 and m2 with weights 12kg and 23kg respectfully, with a rope connecting the two and also a rope pullling m2 with force 50n. I know how to find the tension of the string connecting the 2 and acceleration but how do you do this with respect to friction where the coeff of kenetic friction between each block and the surface is .1? Thanks for the help.


m1---T--- m2---->50N

m1=12kg
m2=23kg
T=17.14

Draw the freebody diagrams of both blocks. What forces act on the block? How can you account for them?

what about accel?
 

1. How is friction calculated?

Friction is calculated using the formula F = μN, where F is the force of friction, μ is the coefficient of friction, and N is the normal force.

2. What is the coefficient of friction?

The coefficient of friction is a dimensionless constant that represents the amount of resistance between two surfaces in contact with each other.

3. How does the mass of the objects affect the friction?

The mass of the objects does not directly affect the friction. However, the normal force, which is equal to the weight of the objects, does affect the friction force.

4. Can friction be completely eliminated?

No, friction cannot be completely eliminated as it is a natural force that occurs when two surfaces are in contact with each other.

5. How can the coefficient of friction be changed?

The coefficient of friction can be changed by altering the surface properties of the objects in contact, such as by adding lubrication or changing the texture of the surfaces.
