Physics Floating and Sinking(11.2) What is floating? density determines whether an object sinks or floats What is sinking If the density is less than the water then the object will float. If it is greater than the water it will sink This is floating This is sinking floating:
When an object
floats, it's buoyant force is equal to its mass. Sinking:
It means submerge
into the water or to
descend to the
bottom. an object sinks if its bouyant force is less than its mass Density is calculted by: mass divided by volume Titanic is one of the
example of sinking. to calculate bouyancy, the equation is:
p=density of fluid
V=volume of object
g=standard gravity on earth The End
