gravitational energy pulling on the wagon
It is easier to pull a wagon on the sidewalk than on grass because the wheels of the wagon roll more smoothly on a hard, flat surface like the sidewalk, compared to the uneven and soft surface of the grass which creates more resistance. The sidewalk provides a stable and firm base for the wheels to move efficiently.
The additional energy source used to pull a wagon when someone is already pulling it could be the wheels interacting with the ground to reduce friction, allowing for smooth movement. Additionally, gravity can assist in pulling the wagon downhill, and wind resistance may also play a role in aiding movement.
The energy used when pulling a wagon is muscular energy generated by your muscles. Your muscles contract and exert force to move the wagon, converting chemical energy stored in your body into mechanical energy to do work.
You are using mechanical energy, which is the energy associated with motion and position of objects. By pulling the wagon, you are exerting a force to move the wagon and your sister, which requires mechanical energy.

Yes, pulling a wagon uphill requires exerting force against gravity, which increases the potential energy of the wagon as it gains height. This potential energy can then be converted back to kinetic energy as the wagon moves downhill.

No, unless the wagon has a 50cc or larger engine propelling it down the sidewalk.

kinetic energy
You can increase the potential energy of a wagon by lifting it to a higher elevation. This increases its gravitational potential energy without changing its mass.
In wagon pulling, there is a harnessing system involved which is attached to the breast of the horse. When a horse pulls forward, the harness, which is attached to the wagon moves with him as well, therefore moving the wagon forward.
When it feels like it
A wagon at the top of a hill will do work when it moves downhill due to the force of gravity pulling it downward. Work is done when a force acts on an object to move it over a distance in the direction of the force, which occurs as the wagon descends the hill.
Depends... they are doing the same amount of work on the wagon/child. HOwever, if you take everything into account... say the diffrent masses of the father and mother, then the bigger of the two would be doing more work.
