... show me that the higher the diver starts from, the greater the depth he reaches. The final dive, depth 34cm hit the bottom of the measuring cylinder, so it probably would have gone a little bit further, but it was still ahead of the other results, therefore it is not too big a problem. I believe that the diver would have reached a greater depth if it had not been for certain forces acting upon it; as it was falling, air resistance slowed it down, when it hit the unbroken water the force against it was very strong, and finally as it was submerged the up-thrust force of the water made it slow down, therefore go less deep. Archimedes Upthrust The volume of water displaced by a body submerged in water is equal to the volume of the body - thus if this weighs less than the body then it will ...
