Tennis Ball Properties

A ball loses mass by losing some of its cloth cover (see opening photo with ball fuzz accumulating around the court slab ball machine and side of the court) We subjected each ball to a rapid wear test by firing it 30 times at high speed from a ball machine (which created and removed fuzz each time) onto a hardcourt slab

Pressure at a depth in a fluid (video)

19-2-2016Sal derives the formula to determine the pressure at a specific depth in a fluid If you're seeing this message Let's say I have that in the fluid at some depth h and since the fluid is completely static-- nothing's moving-- that object that's floating right at that level at a depth of h will also be static

Pressure

When you deal with the pressure of a liquid at rest the medium is treated as a continuous distribution of matter But when you deal with a gas pressure it must be approached as an average pressure from molecular collisions with the walls Pressure in a fluid can be seen to be a measure of energy per unit volume by means of the definition of work
