I have recently gone to an amusement park where i found a strange swing..
The strange thing about it was that its amplitute can be varied by the persons sitting on it..(by pushing the rod near the feet ) .. My doubt is ''how can an internal force affect the system??'' Or is something else happening there...??

When the swing is moving down from left, if the person on left pushes the foot rod, the subsequent amplitude gets increased...

Can i know the physics of this ??

Up close, any scattershot will remove everyone by using a simple hit, despite the fact that for collection, it all packages hardly any hurt in anyway.

yes, i do have the same doubt. I think this is something deal with gravitational energy too. See here, i got some information while googling
