Tension and Velocity

  • #1

Main Question or Discussion Point

Hello, I was recently reading a physics book and was told that, if a string were to hang down with a weight attached to it, its tension would be the mass times gravity. However, if it were to gain some velocity and move from left to right, the tension would increase enough so that the string would be cut. The book doesn't go into further detail. Does the force of the velocity oppose the string? Can someone please explain this to me, possibility showing equations to describe this motion? Thanks

The string will most likely snap. How come you do not do a real world test?

I have watched a few videos, and I lack the sufficient material to produce adequate results (a.k.a poor strings and lack of a weight). I understand that it does happen but not sure why.

What is the path of the object when it is swinging? What do you know about centripetal acceleration?

It's all about the force going into the string and force going out towards the book.
That will result a friction and centripetal acceleration that makes the string snap. ;)
