I was looking at how a problem was solved and what I did not get was why T was put in this equation or n. I'm a little confused on the tension stuff. I do get how friction works and it's coefficiant. n and T is confusing me. The n is the weight of the object on the surface, I know, but why is it in these equations.(adsbygoogle = window.adsbygoogle || []).push({});

Sum of Fx=T-fk=ma

Sum of Fy=n-m1g=0

Thanks
