This is upward force on an object in a liquid.
What is buoyancy?
This is why the feather falls more slowly than the bowling ball when dropped from up high.
What is air resistance?
This is the force working against buoyancy.
What is gravity?
These four forces act on an airplane to lift them and allow them to fly.
What is gravity, lift, thrust and drag? or What is gravity, air pressure, thrust and air resistance?
This is Archimedes Principle.
What is objects that are less dense will float and more dense will sink, and they displace the amount of water equal to their volume.
This is the unit used for weight.
What is a Newton?
The ability of an object to float in a liquid or in the air.
What is buoyancy?
This is Isaac Newton's 3rd law of motion.
What is for every action there is an equal and opposite reaction?
This is the unit used for density.
What is grams/mL or grams/cm3?
A large body of water or small body of water has more buoyant force.
What is large body of water (great volume = more buoyant force)?
