the heaviest person would have to sit nearer the middle
If the two boys of unequal weight are together heavier than two boys of unequal weight the seesaw can be balanced by whichever couple is heaviest sitting nearer to the seesaw's pivot.
they have the same density That would be impossible. The only way to stop moving is to push down with you're feet each time you reach the ground
the fulcrum's in the middle and yes a lever is a seesaw...
The effect would be that the nearer the pivot you have the load, the harder it would be to move the seasaw. The nearere the end, the easier it would be.
A seesaw would be a Class 1 lever. This is because the fulcrum(also known as a pivot) is in the middle of the load and effort.
A seesaw is an example of a first-class lever. The fulcrum, which is the part of the lever that does not move, is in the middle. The resistance, which is the weight (person) you are trying to lift is at one end. The effort, which is the force applied to the lever, is the person sitting on the other end.
because then they would never move because the weight would not be distributed equally and the fat kid would always be on the bottom.
A seesaw is a class one lever.
a seesaw is a lever that is balenced on a fulcrum
A seesaw is a basic lever and by definition it has a fulcrum. Without the fulcrum, there would be no point for the seesaw to operate on.
Seesaw - musical - was created in 1973.
