Density and Buoyancy

Bethke Density and Buoyancy Test

When an object is placed in a fluid with less density than the object, what will happen? it will sink
What are the downwards and upwards forces. Weight - downwards, buoyant force - upwards
What is the abbreviation for weight? Fg
How to calculate downward force? mass(kg) x gravity(9.8m/seconds(squared))
What is the unit for downward force? Newtons (N)
What is buoyancy? An object is buoyant in water due to the amount of water it displaces
If the weight of an object is equal to the weight of the water it displaces what happens? IT FLOATS
If Fg=Fb what happens? THE OBJECT FLOATS
How to calculate buoyant force if you know weight in air and water? Fb=weight in air-weight in water
How to calculate buoyant force without knowing weight in air and water? Density Fluid x Volume Fluid Displaced x Gravity
What is the abbreviation for Buoyancy Fb
What is the density of water? 1g/cm(cubed)
Density Formula D=m/V
