Easy Physics Question: What is the formuals for tension in a cord in Physics?

[edwardraff]

I think it is m1g + m1a = tension is taht correct

 

[Jittles]

Tension is Force.

So if it's hanging and stationary, it is T=F=ma=mg=weight. All the same.

If it is accelerating up or down, it is m(g-a) or m(g+a) depending on which way it is accelerating.

 

[Rahminator]

Yeah, it depends which way it's going.
F = Centripetal Force-Force of Weight ( [(mass*velocity^2)/radius] - mg ) --> going up
or
F = Centripetal Force+Force of Weight ( [(mass*velocity^2)/radius] + mg ) --> going down

Don't take my word for it. I'm failing my high school Physics Honors course right now.

what does centripetal force have to do with anything?

Tension is just a force. Nothing more, nothing less. That's all you need to know.
