After looking a bit further, I have seen the force that moves the swinger. I don't know what it is called, but I know where it comes from.

When you take gravity and tension from the equation and pump your legs, the swinger spins or rotates. When tension is added to the equation, and pump the swinger rotates somewhat, and his/her center of mass moves slightly, almost like he/she is rolling around the swing. This means whatever force spins the swinger is the same force that initiates the movement. I don't know what force this is, so I will leave that up to someone else.

Glad to help!

It has something to do with our center of gravity, which is roughly in our middle, give or take a little, when we move our legs forwards or backwards we change our center of balance, which causes a change in well everything, the swing tries adjusting to this, but gravity + us moving our legs back and forth doesn't let the swing keep us in the center.

Right!

The movement of the swinger's appendages offsets the center of gravity and moves the swing*, and gravity pulls the swing back to the ground (or as close as it can get to the ground.)

*The only thing that I don't get is what force this is.

Kudos to mesawille for getting it straight in your head and understanding (and it's also nice to have a partner in crime :))

Waiting for assistance...

Gravity moves as you swing so if a equal force was made it would not match up with gravity

But how does this start?

It like dividing by infinity but the opposite.

In order for gravity to have moved and pulled you back, you would have had to start moving somehow.
