The short answer is YES! Bigger wheels mean that if the bearing are spinning the same speed, the outside of the wheel is spinning faster than a small wheel.
it goes faster
If going downhill, yes.
because the heavier person has more initeria and therefore the forces that would slow the slider down i.e friction, wind resistance, whatever, have less effect on a heavier person that a lighter person
heaver people would go faster simply because a heaver person could push their weight forward more creating greater acelaration.
The answer is tied up with conservation of momentum; momentum is the product of velocity and mass, so assuming the ball is lighter than the skateboard and rider, the skateboard will go backwards slower than the ball.

if you want it to go faster with no performance parts you will need a lighter person
actually no because the weight keeps it up so no
the heaviest person would have to sit nearer the middle
Yes, it is true. Gravity plays a part in this. You see, it takes a heavier person more effort to burn calories than a lighter person because, because of their larger weight, they are being pulled down more, meaning they fight against gravity, more than the lighter person would. For example if a light and heavy person began and ran up stairs at the same time, it would be harder for the heavier person because more gravity is acting upon them. Hehehe, if the heavy and light person fell down, it would hurt more for the heavier person.
theoretically a heavier person will burn more calories running the same distance than a lighter person. There is more muscle and more mass to be moved on a heavier person therefore more energy is needed.
The faster and heavier that the flow of blood is, the higher pulse rate a person will have because the heart is pumping faster.
because a heavier person has more inertia, and therefore the forces that work to slow the person down, i.e. friction, wind resistance, whatever, will have less effect on an object with more inertia than less inertia
yes, the more weight added on to it will make it faster but one person or the lighter weight will get a head start.
