Buoyancy

Question 1

In what direction do forces act on objects in fluids?

Answer 1

Perpendicularly

Question 2

What is the equation for hydrostatic pressure?

Answer 2

P = ρgh
Hydrostatic pressure = density x gravity x height

Question 3

What is the density of pure water?

Answer 3

1000 kg / m^3

Question 4

What is the value of gravity on earth?

Answer 4

9.81 m / s^2

Question 5

How does the density of objects make objects interact with other objects?

Answer 5

Less dense things float more on top of more dense things

Question 6

How do you find buoyancy force?

Answer 6

Fg = Fb
Fg = ma
Fb = -ρgv

Question 7

How is depth (amount an object is submerged by) calculated?

Answer 7

depth = displaced volume / area of bottom face
