What are the physics involved in a tire swing. (circular motion, but how do i explain it?)?

I need to know the forces applied, the constants, and the overall physics laws involved in a tire swing in motion, with a child in it.



What are the physics involved in a tire swing. (circular motion, but how do i explain it?)?These are the thing involved:



Centripetal Force:



The force required to keep a body moving in a circular path, measured in N (newtons)



Centripetal acceleration:



The acceleration of a body moving in a circular path, measured in ms^2 (metres per second to the minus 2)



Angular velocity:



The time rate of displacment, Omega (the greek symbol, look like a curly W) measured in rads^1 (radians per second)



Period;



The time it takes for one revolution/oscillation, measured in seconds



Frequency: How many revolutions/oscilWhat are the physics involved in a tire swing. (circular motion, but how do i explain it?)?centripetal force.
